I applied through a recruiter. The process took 3 months. I interviewed at Meta (London, England) in Feb 2022
Interview
Process was quite long due to Christmas happening in between but went roughy like this:
1) 45 min recruiter call discussing role and if you have the relevant back ground
2) 45 min technical phone screen incl. 20 min SQL and 20 min product sense, 5 min q&a
3) 2 hours virtual onsite, with 4 back to back 30 min interviews testing product sense (product interpretation and applied data), SQL, quantitative analysis (stats and probability)
Still waiting for them to come back with a decision, have been told to expect one within 1-1.5 weeks of the last interview.
Interview questions [1]
Question 1
Similar to what's already on this page.
- Product sense questions are either about gauging your product knowledge/understanding through questions like how would you measure the success / health of product/feature x
- The other part of product sense is evaluating you on your approach to a problem and how you are able to articulate an executable plan in a data-driven and hypothesis driven manner e.g. questions like if metric that we care about went up/down, how would you investigate this problem?
- SQL questions are leetcode medium-hard level and quantitative analysis is about your understanding of probability and statistics fundamentals.
I applied online. I interviewed at Meta in Jun 2025
Interview
It kicked off with an initial phone screen that jumped straight into technical questions, so you really have to be warmed up—especially on A/B testing: framing the hypothesis, picking primary metrics and guardrails, walking through power/MDE, exposure and unit of randomization.

Question 1
Walk me end-to-end through how you’d run an A/B test for a new feature—start by selecting decision-driven metrics.
Meta's SQL screening tests query skills, optimization, and handling complex datasets. The case round evaluates problem-solving, business insights, and technical solutions to real-world scenarios using data-driven approaches. Its moderate difficulty
I applied online. I interviewed at Meta (Menlo Park, CA) in Mar 2025
Interview
30 min call with recruiter, 1 hour Zoom interview based around product case and SQL/Python database questions. The final round is a loop interview. Two business case interviews, two technical interviews.
Interview questions [1]
Question 1
Please solve this technical question using either R, Python, or SQL. If given a new feature, how would you measure its success rate in an area? If we added another featur,e how would that impact your original measurement.
