I applied through a recruiter. The process took 3 weeks. I interviewed at Meta in Jan 2016
Interview
1 hour phone interview: high level questions on approaching a data analysis problem
6 hour on-site interview with 6 different people
Topics included:
How have you dealt with a difficult person in your current job?
What do you not like about your current job?
SQL questions
Coding on whiteboard: solutions required using recursion and hash tables
How to communicate statistical analysis to non-technical managers
Basic statistics: solving a problem with a two sample t-test, dealing with multicollinearity
Standard questions on machine learning: cross-validation, regularization methods
More time and weight was given to programming questions rather than statistical questions.
Interview questions [1]
Question 1
Write an SQL query that makes recommendations using the pages that your friends liked. Assume you have two tables: a two-column table of users and their friends, and a two-column table of users and the pages they liked. It should not recommend pages you already like.
The Interview Process is very structured -
First Tech Screening round - 45 mins (usually can extend a bit depending on the interviewer)
- 2 SQL Questions ( Medium to Hard ) - based on Joins
Full Loop - 4 rounds 45 mins each.
- SQL
- Behavioral
- Analytical Execution - stats & prob, A/B testing, case study
- Analytical Reasoning - Case study

Question 1
Questions on Bayes Theorem, Probability distribution, etc.
A friend who worked at Meta recommended I apply, which led to a direct connection with the hiring team. My interview journey included a technical screen focused on product metrics and a behavioral interview. The final round faced me with a practical question about measuring success for a new push notification feature. Funny enough, I had found similar questions in the company-specific prompt section on PracHub, which helped me approach it confidently. Ultimately, I received an offer but decided to decline it for personal reasons.

Question 1
How would you measure the success of a new push notification feature on Instagram? Walk through your primary metric, guardrail metrics, how you'd design the A/B test (randomization unit, sample size, duration), and the tradeoffs between short-term engagement lift and long-term retention impact.
I applied online. The process took 6 months. I interviewed at Meta
Interview
Completed 3 rounds of the process, which includes the initial recruiter screen, technical, full loop, and team matching.
Couldn't move past the full loop interview. The interview was very engaging, and I actually enjoyed working through the cases. No crazy questions.
