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]
Question 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.
It's all organized. Be prepared to showcase your depth of thinking. Two analytical rounds will make you think on your ability to solve probability and experimentation problems. Have a structure for everything
