I applied through a recruiter. The process took 4 weeks. I interviewed at Meta (Menlo Park, CA) in Jan 2018
Interview
I was contacted by the recruiter with whom I had a brief 10-15 minute phone call. Then we went ahead with a virtual interview with another data scientist. The online interview consisted of writing code in a text editor answering some data analysis questions such as how do you measure user engagement, how do you measure the effectiveness of a new feature. The interviewer was looking more for the thought process than actual execution of the code.
I got through the online interview and was scheduled for the onsite interview loop consisted of five interviews of 30 minutes each. Two required product analytics brainstorming, one was statistics and probability, and two more were performing ETL using SQL and also performing analysis using SQL. There was a lunch break of an hour in between.
I had a great experience throughout the interview process and the recruiter helps out a lot by emailing preparation materials and calling to discuss the material. Unfortunately I did not get through the last interview. I was not given a reason, just that there were many applicants.

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
