I applied online. The process took 2 months. I interviewed at Meta (London, England) in Jan 2018
Interview
Applied online and received a call back from a recruiter within about two weeks. There was an initial online coding interview and another call with the recruiter. The onsite was schedule about month later and was an all-day affair with a series of interviews with different members of the team, including a one-on-one with the team lead, then technical interviews on on data science methods and causal inference, software engineering, basic probability (like coin flipping problems), and data exploration.
Interview questions [4]
Question 1
You have a set of pairs of integers representing intervals (inclusive). What is the integer or set of integers that are included in the largest number of the intervals?
You have a length-n list of pairs of integers, such as (1,2) (3,4) (6,8). Write a (recursive) algorithm that produces every possible n-digit concatenation of these numbers (e.g., 136, 138, 146, 148, 236, 238, 246, 248).
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
Interview questions [1]

Questions on Bayes Theorem, Probability distribution, etc.
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.
