I applied through an employee referral. The process took 4 weeks. I interviewed at Meta (Dublin, Dublin) in May 2015
Interview
Phone screening, then online interview (coding questions), then 4 more onsite interviews ('data science'/modelling interview, another 2 coding interviews, and statistical analysis interview). Some of the interviewers were very kind and nice, some were showoffs and annoying. You are given more chance to show your coding skills than your data analysis/statistics modelling ones, which is a shame.
Interview questions [1]
Question 1
Screening was basic concepts questions. Coding interview were part live coding in a chat, others on a white board. Things like implement a sparse matrix, or questions from the coding interview book. Modelling interview was to go through a case study step by step and analyse a problem + model its solution. Statistics interview was more like a statistics course quiz, defining terms, solving statistical equations etc.
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
