Facebook Meta Interview Questions: Complete 2026 Guide for Job Seekers

What if the difference between landing your dream job at Facebook and getting another rejection email came down to how you answered just three behavioral questions? It sounds dramatic. But when it comes to interview questions in Facebook’s hiring process, it’s closer to the truth than you think.

What Makes Facebook (Meta) Interviews Different in 2026

Understanding the interview questions in Facebook’s hiring process starts with recognizing what makes Meta different. Landing a job at Meta isn’t just about joining a tech giant; it’s about plugging into a global network that connects billions of people. With a workforce of nearly 72,000 employees, the company continues to attract top talent eager to make a large-scale impact. But getting in requires understanding a unique interview culture shaped by one core principle: “Move Fast.”

This philosophy isn’t just a poster on the wall. It translates directly into an interview process that values speed, efficiency, and decisive problem-solving. Interviewers are trained to push candidates for optimal solutions quickly. They want to see how you think on your feet, adapt to new information, and drive toward a result without getting bogged down.

The Game-Changer: AI-Assisted Coding Interviews

The biggest shift in Meta’s 2026 hiring process is the introduction of the AI-assisted coding round. This isn’t a simple chatbot. It’s a full-fledged IDE environment where you collaborate with an AI assistant (like Llama 4 or GPT-4o mini) to solve complex problems. This new format replaces one of the traditional coding interviews and is designed to simulate a real-world engineering workflow more closely.

Candidates who excel here don’t just accept the AI’s suggestions. They critically evaluate them, justify their choices, and steer the AI, demonstrating a higher level of architectural thinking. This is a massive departure from the sterile, white-board coding of the past and a key area where you can gain an edge.

How Meta’s Interview Process Stacks Up

While all FAANG interviews are challenging, Meta’s process has distinct characteristics. It’s highly centralized, meaning you get one shot at the general hiring pool every 6-12 months, unlike Amazon where you might interview with multiple teams.

Feature	Meta (Facebook)	Google	Amazon	Apple
Process Style	Centralized, team-agnostic	Centralized, team-matching later	Decentralized, team-specific	Decentralized, highly team-specific
Key Focus	Speed, execution, behavioral	Algorithmic depth, generalists	Leadership Principles, customer obsession	Deep domain expertise, secrecy
Pace	Fast (4-8 weeks typical)	Slow (can take months)	Varies, can be very fast	Slow and deliberate
Unique Element	AI-Assisted Coding Round (2026)	Hiring committee review	The “Bar Raiser” interviewer	Multiple, role-specific interviews

Meta’s Interview Process: A Step-by-Step Timeline

The path to a job at Meta is a marathon, not a sprint. While the company values speed, its hiring process is a structured journey designed to rigorously evaluate candidates from multiple angles. The entire process can take anywhere from four weeks to five months, so patience and preparation are your best allies.

Here’s a clear, step-by-step breakdown of what you can expect after you submit your application.

Step 1: The Recruiter Call

This initial 15-30 minute conversation is more than just a formality. The recruiter is making a first-pass assessment of your background, your motivations, and your communication skills. They want to understand why you’re interested in Meta and ensure your experience aligns with the roles they’re trying to fill.

Insider Tip: This is your first chance to make a strong impression. Be prepared to talk about a specific project you’re proud of and have thoughtful questions ready about Meta’s culture and challenges. This is also where the salary conversation begins, so do your research beforehand.

Step 2: The Technical Phone Screen (TPS)

This is your first real technical hurdle. The TPS is a 45-minute interview, typically conducted on CoderPad. You’ll face two coding questions of LeetCode easy or medium difficulty, and you’ll have about 35 minutes to solve them. A crucial detail: Meta often disables code execution in CoderPad during this screen. You must be confident in your ability to write clean, bug-free code and verbally walk through your logic without a compiler to lean on.

Step 3: The Onsite Interviews (The “Loop”)

If you pass the phone screen, you’ll advance to the main event: the onsite loop. This is a series of 4-5 interviews packed into a single day, designed to provide a 360-degree view of your abilities. For senior roles (E6+), this may be preceded by a Leadership Assessment interview focused on your experience with cross-functional partnerships, conflict resolution, and driving results.

A typical onsite loop for a software engineer includes:

• Two Coding Interviews: Similar to the phone screen but potentially more challenging. As of 2026, one of these will likely be the new AI-assisted round.
• One System Design Interview: A deep dive into building scalable systems. This is critical for mid-level and senior roles (E5+).
• One Behavioral Interview: Also known as the “Jedi” interview. This is a deep exploration of your past experiences, focusing on collaboration, conflict, and impact.

Onsite Interview Timeline

Interview Round	Duration	Primary Focus	Key to Success
Coding Round 1 (Traditional)	45 mins	Data Structures & Algorithms	Clear communication, optimal solution
Coding Round 2 (AI-Assisted)	60 mins	Problem-solving with AI tools	Critical evaluation of AI suggestions
System Design	45-60 mins	Scalability, architecture, trade-offs	Thinking out loud, structured approach
Behavioral (“Jedi”)	45 mins	Culture fit, collaboration, impact	Specific examples using the STAR method

After the loop, the interviewers convene for a debrief session. They share their feedback and collectively decide whether to extend an offer. This decision-making process is swift, and you can typically expect to hear back from your recruiter within a week.

Technical Coding Questions: What to Expect and How to Prepare

Among all the interview questions in Facebook’s process, the coding interview is the backbone of Meta’s technical assessment. It’s where you prove you have the fundamental engineering skills to build, maintain, and innovate on products used by billions. Success here isn’t just about finding the right answer—it’s about how you get there.

Understanding the Format

Meta’s coding rounds are highly standardized. You’ll be in a CoderPad environment, which is a collaborative code editor. As mentioned, code execution is often turned off, so you must be able to mentally compile and debug your code. You are expected to solve two problems in roughly 35-40 minutes, which means you have less than 20 minutes per question. This pace demands both accuracy and speed.

Top Coding Questions with Difficulty Ratings

While specific questions change, the patterns remain consistent. Your preparation should focus on these core areas. Here are some of the most frequently encountered problems at Meta, along with their typical difficulty level.

Question Category	Example Problem	Difficulty
Arrays & Strings	Merge Overlapping Intervals	Medium
Arrays & Strings	Move Zeros to the Left	Easy
Arrays & Strings	Valid Palindrome II	Easy
Arrays & Strings	Minimum Window Substring	Hard
Linked Lists	Reverse a Linked List	Easy
Linked Lists	Merge K Sorted Lists	Hard
Linked Lists	Remove Nth Node From End of List	Medium
Trees & Graphs	Binary Tree Right Side View	Medium
Trees & Graphs	Convert Binary Tree to Doubly Linked List	Medium
Trees & Graphs	Number of Islands	Medium
Heaps	Find Median from Data Stream	Hard
Dynamic Programming	Longest Palindromic Substring	Medium
Matrix	Spiral Matrix	Medium
Backtracking	Subsets	Medium
Design	LRU Cache	Medium

Sample Question Deep Dive: 2D Spiral Array

Let’s break down a classic Meta question: Given an integer n, generate a square matrix filled with elements from 1 to n^2 in spiral order.

The key is to think in layers. You can solve this by simulating the spiral path, moving right, then down, then left, then up, and shrinking the boundaries of the matrix with each completed layer. This approach is intuitive and less prone to off-by-one errors than trying to calculate the position of each number mathematically.

# Python solution for Spiral Matrix
def generateSpiralMatrix(n):
    if n <= 0:
        return []
    matrix = [[0 for _ in range(n)] for _ in range(n)]
    num = 1
    top, bottom, left, right = 0, n - 1, 0, n - 1

    while top <= bottom and left <= right:
        # Move right
        for i in range(left, right + 1):
            matrix[top][i] = num
            num += 1
        top += 1

        # Move down
        for i in range(top, bottom + 1):
            matrix[i][right] = num
            num += 1
        right -= 1

        # Move left
        if top <= bottom:
            for i in range(right, left - 1, -1):
                matrix[bottom][i] = num
                num += 1
            bottom -= 1

        # Move up
        if left <= right:
            for i in range(bottom, top - 1, -1):
                matrix[i][left] = num
                num += 1
            left += 1

    return matrix
        

Complexity Analysis: The time complexity is O(n^2) because we visit each cell in the matrix exactly once. The space complexity is O(1) if we don’t count the output matrix itself; otherwise, it’s O(n^2). This is an optimal solution.

The 2026 AI-Assisted Coding Round

This new 60-minute round is a different beast. Instead of a blank slate, you’re dropped into a small, existing codebase (a few hundred lines across several files) and asked to perform a series of tasks: review code, fix a bug, add a feature, and then discuss scaling. You have an AI assistant at your disposal.

The goal is not to test your ability to prompt an AI. It’s to test your ability to *leverage* an AI. Can you spot when the AI’s suggestion is suboptimal? Can you guide it toward a better solution? Can you explain the trade-offs of the code it generates? Blindly copying and pasting is the fastest way to fail.

Aspect	Traditional Coding Round	AI-Assisted Coding Round
Task	Solve 2 isolated LeetCode problems	Evolve a single, multi-file codebase
Environment	Simple editor, no execution	IDE-like, with file tree and AI tools
Core Skill	Algorithmic problem-solving	Code comprehension, debugging, architectural reasoning
Failure Mode	Can’t find optimal solution	Blindly trusting the AI, poor code review

Mastering Facebook’s Behavioral Questions: The STAR Method

Behavioral interview questions in Facebook’s process are just as critical as technical ones. If the coding interview is about what you can do, the behavioral interview is about who you are. At Meta, this round—often called the “Jedi Interview”—is just as critical as any technical screen. They aren’t just hiring a coder; they are hiring a future teammate, a collaborator, and a potential leader.

Why Behavioral Questions Matter So Much at Meta

Meta’s culture is built on a set of core values: Be Bold, Focus on Impact, Move Fast, Build Social Value, and Be Open. The behavioral interview is a systematic process to find evidence of these values in your past experiences. They want to know how you navigate conflict, handle failure, and drive projects forward. A brilliant engineer who can’t collaborate effectively won’t last long in Meta’s fast-paced, team-oriented environment.

The STAR Method: Your Framework for Compelling Stories

The STAR method is a structured way to answer behavioral questions that turns vague claims into compelling narratives. It’s the framework Meta interviewers are trained to listen for. Don’t just say you’re a good collaborator; prove it with a story.

• Situation: Briefly set the scene. What was the context? What project were you on? (1-2 sentences)
• Task: Describe your specific responsibility. What was the goal or problem you were tasked with solving? (1 sentence)
• Action: Detail the specific, individual steps *you* took. Use “I” statements, not “we.” This is the most important part of your answer. (3-5 sentences)
• Result: Quantify the outcome. What was the impact of your actions? Use metrics and data whenever possible. (1-2 sentences)

Top Behavioral Questions with Complete STAR Answers

Here’s how to apply the STAR method to some of the most common and challenging behavioral questions asked at Meta.

1. Tell me about a time you had a conflict with a teammate.

Why they ask it: They want to see if you are mature, professional, and can resolve disagreements constructively without escalating or shutting down.

Situation: On the Ads delivery team, a senior engineer and I had a fundamental disagreement about a new caching strategy. He advocated for a complex, multi-layered solution he believed would be more performant, while I proposed a simpler, more direct approach that I argued would be easier to maintain and debug.

Task: My task was to ensure we chose the right long-term solution, balancing performance with operational health, and to get alignment so the project could move forward without friction.

Action: First, I listened carefully to his proposal to fully understand his perspective. Then, instead of debating opinions, I proposed we settle it with data. I spent a day building a lightweight proof-of-concept for both approaches. I created a suite of benchmarks that measured not just raw latency but also memory usage and, crucially, the time it would take to identify a cache-invalidation bug.

Result: My benchmarks showed that his solution was indeed 5% faster in ideal conditions, but it used 20% more memory and made debugging significantly harder. I presented my findings in a short document, acknowledging the performance trade-off but recommending my simpler approach for its maintainability. He saw the data-driven argument, agreed it was the right call, and we moved forward with my proposal. The feature launched smoothly, and we later traced and fixed a production issue in under 15 minutes, a process that would have taken hours with the more complex design.

2. Describe a time you failed.

Why they ask it: They are testing for self-awareness, humility, and your ability to learn from mistakes. A good answer shows ownership, not blame.

Situation: Early in my career, I was responsible for a code change that was supposed to improve the efficiency of a data processing pipeline. I was confident in my logic and, in a rush to meet a deadline, I pushed the change after only running basic unit tests.

Task: My task was to deploy the efficiency improvement without disrupting the pipeline, which processed critical data for our analytics dashboard.

Action: My change introduced a subtle bug that only manifested with a specific data format. It caused the pipeline to fail silently overnight. When I came in the next morning, the dashboard was stale, and several teams were blocked. I immediately took ownership, rolled back the change to restore the service, and then spent the next two hours performing a post-mortem to understand the root cause. I identified the gap in my testing strategy and realized I had made an assumption about the input data.

Result: The immediate result was a minor data delay, but the long-term impact was positive. I presented my post-mortem to the team, highlighting the need for more robust integration testing for that pipeline. I then personally implemented a new set of integration tests that would have caught my bug. This failure taught me a valuable lesson about the dangers of making assumptions and the importance of thorough testing, a principle I have carried with me ever since.

3. How have you used data to influence a decision?

Why they ask it: Meta is a data-driven company. They want to see that you make decisions based on evidence, not just intuition.

Situation: The product team wanted to build a new “Recommended for You” feature on our platform’s homepage, believing it would drive engagement. The engineering team was skeptical about the effort versus the potential reward.

Task: My task was to determine if this feature was worth the significant engineering investment and to provide a data-backed recommendation to leadership.

Action: Instead of building the full feature, I proposed we run a lightweight A/B test. I built a simple version of the recommendation engine that used a basic algorithm. We rolled it out to 1% of users. I tracked not just click-through rates on the recommendations but also overall session time and the rate at which users returned the next day.

Result: The data was surprising. While users did click on the recommendations, the overall session time for the test group did not increase. More importantly, their next-day return rate was slightly *lower* than the control group. My analysis suggested the feature was a distraction, not an enhancement. I presented this data to the product team, and we collectively decided to pivot away from the homepage feature and instead integrate recommendations more contextually within the user’s existing workflow. This saved us an estimated three months of engineering time.

Questions YOU Should Ask the Interviewers

The end of the interview is your turn. Asking thoughtful questions shows your engagement and helps you decide if Meta is the right fit for you. Avoid questions about salary or basic facts you could have Googled.

Good Questions to Ask	Why It Works
“What’s the biggest technical challenge your team is facing right now?”	Shows you are thinking about their problems and are eager to contribute.
“Can you tell me about a time someone on your team was promoted? What did they do to get to the next level?”	Demonstrates you are career-oriented and want to understand the path to growth.
“How does your team handle technical debt?”	Gives you insight into their engineering culture and priorities.
“What does success look like for this role in the first six months?”	Shows you are results-oriented and want to make an impact quickly.
“What surprised you the most when you first joined Meta?”	A great personal question that can reveal a lot about the company culture.

System Design Interviews: For Senior Engineers (E5+)

The system design interview is the gateway to senior engineering roles at Meta. While junior engineers are tested on algorithms, senior candidates are expected to demonstrate architectural thinking. This isn’t about writing code; it’s about designing the blueprint for systems that can serve billions of users.

When System Design Matters

This round is typically reserved for candidates interviewing for E5 (Senior) level and above. In this 45-60 minute session, you’ll be given a vague, open-ended prompt and expected to lead the conversation. The interviewer is evaluating your ability to handle ambiguity, gather requirements, compare trade-offs, and sketch out a high-level, scalable architecture.

Common System Design Questions at Meta

Meta’s design questions are often based on its own products and challenges. You should be familiar with the architecture behind large-scale social media features.

• Design News Feed: A classic question that tests your understanding of feed generation, ranking, and delivery.
• Design Instagram: A broad question that could involve designing the photo upload system, the social graph, or the feed.
• Design Messenger / WhatsApp: Focuses on real-time messaging, presence status, and end-to-end encryption.
• Design a URL Shortener: A seemingly simple problem that hides deep complexities in hash generation and scalability.
• Design Live Comments: Tests your ability to handle a high-throughput, low-latency system with a massive number of concurrent users.
• Design a “Free Food” App: A Meta-specific question about designing a service to handle massive, spiky traffic, like distributing millions of items in minutes.

A Framework for Approaching System Design Problems

Don’t jump into solutions. A structured approach shows maturity and ensures you don’t miss critical components. Follow these steps to guide your conversation.

1. Clarify Requirements & Assumptions: Ask questions to narrow the scope. Who are the users? What are the key features? What is the expected scale (e.g., users, requests per second)? State your assumptions explicitly.
2. Back-of-the-Envelope Estimation: Do some quick math to estimate storage, bandwidth, and compute needs. This will inform your technology choices.
3. High-Level Design (API & Data Model): Define the main API endpoints (e.g., `POST /feed`, `GET /feed`) and sketch out the primary database tables or data structures.
4. Detailed Component Design: Dive into the individual components. How will you load balance the traffic? Where will you use caching? Will you use a SQL or NoSQL database? Why? How will you handle media storage (e.g., photos, videos)?
5. Identify Bottlenecks & Scale: Discuss potential bottlenecks. How will you scale the database? Will you use sharding or replication? How will you ensure high availability and fault tolerance?

Sample Walkthrough: Design News Feed

Start by clarifying: Is the feed chronological or ranked? How many friends does a user have on average? How many daily active users? Let’s assume a ranked feed for 1 billion DAUs. For the high-level design, you’d have a web server tier, an application server tier, and a database tier. The core of the problem is the “fan-out” on write vs. “fan-in” on read. For a celebrity with millions of followers, pushing a post to every follower’s feed on write is infeasible (fan-out on write). Instead, you’d likely use a hybrid approach: for regular users, you fan-out on write. For celebrities, you fetch their posts at the time the user loads their feed (fan-in on read). You’d use a distributed cache like Redis to store the pre-computed feeds for active users to ensure low latency.

Tailoring Your Preparation by Role and Level

Not all Meta interviews are created equal. The company’s expectations shift dramatically based on the role and seniority you’re targeting. A junior engineer’s path to success looks very different from that of a senior leader. Tailoring your preparation is essential.

Software Engineer (E3-E5): The Builder

For junior to mid-level roles, the focus is squarely on your ability to execute. Can you take a well-defined problem and deliver clean, efficient, and bug-free code? Can you communicate your thought process clearly while doing so?

• Primary Focus: Coding proficiency is paramount. You should be able to solve LeetCode medium problems consistently and quickly. Your behavioral interviews will focus on your ability to be a good teammate and your eagerness to learn.
• Question Distribution: Expect a heavy emphasis on coding rounds (both traditional and AI-assisted). You will likely get one system design question at the E5 level, but it will be more about component-level design rather than large-scale architecture.
• What Success Looks Like: Writing optimal, clean code with no major bugs. Clearly explaining your data structure and algorithm choices. Demonstrating a collaborative and coachable attitude.

Senior/Staff Engineer (E6-E7): The Architect and Leader

At the senior and staff levels, your ability to code is assumed. The interviews shift to evaluating your ability to lead, influence, and think at scale. You are no longer just a builder; you are an architect and a multiplier for the team.

• Primary Focus: System design and leadership. You must be able to drive a system design conversation from ambiguity to a concrete plan. Your behavioral interviews will probe your experience in mentoring junior engineers, leading complex projects, and resolving cross-functional conflicts.
• Question Distribution: You will face at least two challenging system design or architecture rounds. Your coding rounds may involve more complex, multi-part problems. Expect a dedicated Leadership Assessment interview for E6+ roles.
• What Success Looks Like: Designing robust, scalable systems while clearly articulating trade-offs. Providing specific, high-impact examples of your leadership and influence. Demonstrating a deep understanding of how your technical decisions impact the business.

Insider Tips from Meta Interviewers

“Listen for the hints.” An anonymous Meta interviewer shared, “We are literally trained to give good hints. If your interviewer says, ‘Are you sure that’s the most optimal way?’ or ‘What about the memory usage here?’, they are handing you a lifeline. Don’t ignore it.”

“We want to see you think.” Another hiring manager noted, “The worst thing you can do is stay silent for five minutes and then produce a perfect solution. We need to hear your thought process. Talk through the brute-force solution first, then optimize. It shows us how you approach problems.”

“Behavioral is not a soft skill round.” A senior engineer on a hiring committee explained, “We weigh the behavioral round just as heavily as the technical ones. A brilliant jerk who can’t work with a team is a net negative for us. We are looking for signals of ownership, humility, and a focus on impact.”

What to Expect: Compensation and Timeline

Understanding the compensation structure and interview timeline can significantly reduce the anxiety of the process. While Meta is known for its competitive pay, the total compensation is a package deal. The interview process itself can vary in length, so knowing the typical milestones is key.

Average Salary Ranges by Level (2026 Estimates)

Meta’s compensation is broken down into three main components: base salary, an annual bonus target, and Restricted Stock Units (RSUs) that vest over four years. The following are estimated total compensation figures for software engineers in a high-cost-of-living area like the San Francisco Bay Area. Note that these can vary based on location, experience, and interview performance.

Level	Title	Estimated Total Compensation (Annual)
E3	Software Engineer	$180,000 – $220,000
E4	Software Engineer	$250,000 – $350,000
E5	Senior Software Engineer	$350,000 – $500,000
E6	Staff Software Engineer	$500,000 – $800,000
E7	Senior Staff Software Engineer	$700,000 – $1,200,000+

Interview Timeline Expectations

While some candidates move through the process in as little as four weeks, it’s more common for the journey to take a couple of months. Factors like role seniority, team availability, and internal headcount approvals can all affect the timeline.

• Application to Recruiter Call: 1-2 weeks
• Recruiter Call to Phone Screen: 1-3 weeks
• Phone Screen to Onsite Loop: 2-4 weeks
• Onsite Loop to Offer: 1-2 weeks

Negotiation Strategies

Meta has a reputation for being an aggressive negotiator. Your strongest leverage comes from having a competing offer from another top-tier company (like Google, Apple, or a well-funded startup). Always wait until you have the official offer before you begin to negotiate.

Insider Tip: Never give the first number. When the recruiter asks for your salary expectations, politely deflect by saying you’d first like to understand the full scope of the role and the compensation band. If you have a competing offer, present it confidently and be prepared to walk away. Remember that RSUs are often more negotiable than base salary.

Your 4-Week Preparation Plan

A structured approach to preparation can make the difference between feeling overwhelmed and feeling confident. Here is a suggested 4-week roadmap to get you interview-ready. Adjust it based on your own strengths and weaknesses.

Week 1: Foundation Building

• Data Structures & Algorithms Review: Go back to basics. Solidify your understanding of arrays, strings, linked lists, trees, graphs, heaps, and hash tables.
• Practice Easy Problems: Solve 10-15 LeetCode easy problems focused on the data structures you just reviewed. The goal is to build confidence and speed.
• Research Meta: Deeply understand Meta’s mission, products, and core values. Start formulating your answer to “Why Meta?”

Week 2: Skill Development

• Tackle Medium Problems: Move on to LeetCode medium problems, focusing on the categories most frequently asked by Meta (see our list above). Aim for 15-20 problems.
• Draft STAR Stories: Write out 5-7 detailed stories using the STAR method for the most common behavioral questions. Practice saying them out loud.
• Mock Behavioral Interviews: Partner with a friend or use a platform to do at least one mock behavioral interview. Get feedback on your stories and delivery.

Week 3: Advanced Practice

• System Design Fundamentals: If you are an E5+ candidate, start studying system design. Read articles, watch videos, and understand the core concepts like load balancing, caching, and database scaling.
• Attempt Hard Problems: Try a few LeetCode hard problems. Even if you can’t solve them optimally, the struggle will teach you advanced techniques.
• Full Mock Interviews: This is critical. Do at least two full mock interviews (one coding, one system design/behavioral) with experienced interviewers on platforms like interviewing.io or Pramp.

Week 4: Final Polish

• Review and Refine: Go over the problems you struggled with. Review your STAR stories. Make sure your “Why Meta?” answer is polished.
• Simulate the Environment: Practice coding in a plain text editor or CoderPad without running your code. Time yourself strictly.
• Prepare Your Questions: Finalize the list of thoughtful questions you will ask your interviewers.
• Rest: Don’t cram the day before. Your brain needs to be fresh. Get a good night’s sleep.

What NOT to Do: Common Interview Pitfalls

Sometimes, avoiding mistakes is just as important as demonstrating your skills. Meta interviewers are trained to spot red flags. Here are some of the most common pitfalls that can sink your candidacy.

Technical Mistakes

• Jumping to Code: Never start coding without first clarifying the problem, discussing your approach, and considering edge cases. It shows a lack of discipline.
• Poor Communication: Don’t code in silence. Articulate your thought process, even if you’re stuck. The interviewer is evaluating how you think and collaborate.
• Ignoring Hints: If your interviewer gives you a hint, take it. It means you’re either going down the wrong path or missing a key insight. Arguing with the interviewer is a major red flag.
• Blindly Trusting the AI: In the AI-assisted round, accepting a flawed suggestion from the AI without questioning it is worse than not using the AI at all. It shows a lack of critical thinking.

Behavioral Red Flags

• Badmouthing Past Employers: It’s unprofessional and makes you look like a complainer. Frame past challenges as learning opportunities, not grievances.
• Taking All the Credit: Using “I” is important in the STAR method, but failing to acknowledge the contributions of your team makes you seem arrogant and not a team player.
• Lack of Curiosity: Not having any questions for the interviewer signals a lack of genuine interest in the role and the company.
• Vague, Generic Answers: If your answers could apply to any company, you haven’t done your homework. Your motivation for joining Meta should be specific and well-reasoned.
