Meta Data Scientist Interview Guide
Updated by Meta candidates
Written by Kevin Landucci, Subject Matter Expert, InterviewingMeta data science interviews are tough.
They test your product sense, analytical reasoning, and ability to make data-driven decisions under ambiguity.
About 80% of the process focuses on case studies and analytics reasoning—the core of how Meta evaluates data scientists.
This guide breaks down every stage of the process, with example questions and preparation tips to help you perform at your best.
Interview process
The Meta Data Scientist interview process typically takes 4–6 weeks from start to finish.
The process tests both your technical depth and product judgment through 3 main stages:
- Recruiter screen: Background, motivation, and culture fit
- Technical screen: SQL and product sense
- Final round: Case studies, an SQL round, and a behavioral interview
Most interviews take place virtually, but senior or specialized candidates may have onsite rounds.
Browse recent Meta Data Science questions to get a sense of their format and difficulty.
This guide was reviewed by current and former Meta Data Scientists. It reflects Meta’s latest interview structure and evaluation criteria.
Recruiter screen
The recruiter screen is a short 30-minute conversation that focuses on your background, motivation, and fit for Meta’s product analytics culture.
Recruiters want to confirm that you understand Meta’s mission and can clearly explain how your experience aligns with data science work at scale.
Meta emphasizes ownership and communication, so expect questions about projects you’ve led end-to-end, how you use data to solve problems, and what motivates you to join the company. Recruiters may also discuss compensation expectations and your interview timeline.
Sample questions
- Why do you want to work at Meta?
- Tell me about a project you owned from start to finish.
- How have you used data to solve a business problem?
- Describe your experience with SQL and experimentation.
- What are your compensation expectations?
Prepare a concise 45-second summary of your background. Highlight measurable results and end with why Meta’s data-driven culture excites you—it shows confidence and clarity early on.
Technical screens
The technical screen at Meta tests how well you can translate data into product insights.
You’ll complete an SQL challenge and a product sense interview designed to reveal your reasoning process and analytical depth.
Interviews are typically held on CoderPad or a similar platform. You’ll write real SQL queries—not pseudocode or algorithmic solutions.
Meta interviewers look for clear logic, structured thinking, and awareness of trade-offs rather than perfect syntax.
SQL assessment
Expect 1–2 SQL problems using small datasets from products like Facebook, Instagram, or Messenger.
Questions test your ability to filter, aggregate, and organize data—not complex joins or window functions.
Topics to review:
- Joins and subqueries
- Aggregates and date functions
- Grouping and filtering
- CASE statements
Example prompt
Dataset: Messenger call logs
- Find users who called three or more people last week.
- What percentage of active users in France made or received a call yesterday?
Review SQL interview questions before your interview. Focus on writing clean, readable queries and explaining your assumptions aloud—it shows confidence and clarity.
Product sense interview
The product sense round tests how you analyze product decisions and define success metrics.
Meta’s data scientists work closely with product teams, so interviewers want to see both business intuition and technical thinking.
Expect open-ended questions about product performance, growth, or feature design. Your goal is to frame the problem, identify key metrics, and explain your reasoning step by step.
Example prompt
Messenger currently supports 1:1 calls. The product team wants to add group calls. How would you approach this decision?
Follow-up questions may include:
- Who would you roll this out to first?
- What metrics would you monitor?
- How would you design an A/B test?
- If data isn’t available, how else could you measure impact?
Study Meta’s A/B testing frameworks, especially unit and cluster randomization. These concepts appear frequently in both the technical and final case study interviews.
Final round
The final interview loop at Meta mirrors real Meta product challenges and includes 4 interviews:
- 2 case studies (analytics reasoning and analytics execution)
- 1 SQL interview
- 1 behavioral interview
You’ll work through ambiguous scenarios, choose the right metrics, and explain your reasoning using data.
Case study interviews
Case studies are the most important part of the Meta data scientist interview. They reveal how you structure problems, test hypotheses, and communicate insights.
There are 2 case study types:
- Analytics reasoning: Planning experiments and metrics before launch
- Analytics execution: Analyzing performance and optimization after launch
Brush up with our Data Science interview prep course before practicing case studies. It includes frameworks used by current Meta Data Scientists.
Example reasoning prompt
We want to create a “Restaurants you may like” feature. How would you measure success and design a recommendation model?
Example execution prompt
A news product has over two billion daily users. Users can comment on stories. What does the distribution of comments per user look like, and how would you interpret it?
Additional case study examples
- Investigate a sudden 10% drop in Facebook’s daily post views.
- How would you evaluate fake news’ impact on Facebook users?
- Balance Instagram ads and follower posts, monitoring their effectiveness.
- Analyze a news site where comments per user per day increased from four to five.
Expect follow-up questions testing your understanding of statistics and causal reasoning. Review difference-in-differences, A/B testing, and causal inference—Meta interviewers emphasize these methods.
SQL interview
The final SQL interview revisits fundamentals. The goal is to demonstrate logical structure, efficiency, and clear communication rather than obscure syntax tricks.
Core topics to review:
- Aggregations
- Subqueries
- Conditional logic
- Joins
- Date-based filtering
Avoid advanced topics like window functions or DDL—they’re not part of Meta’s scope.
Sample questions
- Find users who called three or more people last week.
- Calculate the share of Messenger users active yesterday.
- Identify users with friends-of-friends who accepted requests.
Speak aloud while writing queries. Interviewers value transparency—explaining each step shows your reasoning and builds credibility.
Probability and statistics
There’s no dedicated statistics round, but these questions often appear in case studies or SQL interviews—especially for senior roles.
Meta expects working knowledge of probability, regression, and experimentation design.
Key areas to review:
- A/B test design and interpretation
- Descriptive statistics (mean, median, percentiles)
- Central Limit Theorem
- Linear regression
- Conditional probability and Bayes’ theorem
- Causal inference and confounding variables
Sample questions
- Explain Bayes’ theorem.
- Implement k-means clustering.
- How do you handle network effects in experiments?
- When would you use difference-in-differences?
Behavioral interview
The behavioral interview evaluates collaboration, ownership, and resilience—traits Meta prizes in every data scientist. Even though it’s less technical, this round can make or break an offer decision.
Interviewers look for reflection, accountability, and data-driven leadership. They want to see how you work through ambiguity, influence others, and learn from setbacks.
Focus areas:
- Navigating ambiguity
- Influencing stakeholders
- Cross-team collaboration
- Learning from failure
Sample questions
- Tell me about a time you influenced a stakeholder who disagreed with you.
- Describe a project that didn’t go as planned—what did you learn?
- How do you handle conflicting priorities?
- Why do you want to work at Meta?
Review Meta’s engineering behavioral interview course for guidance on framing stories. Focus on clarity, impact, and what you learned.
Meta DS interview prep
Success in Meta’s data scientist interview comes from structured, targeted preparation. You’ll need to balance technical depth with strong product intuition.
