I applied through a recruiter. The process took 1 day. I interviewed at Meta (New York, NY) in Mar 2017
Interview
Conducted through external recruiter, then video chat with member of FB data team. Asked soft behavioral questions and then some technical questions about Python and SQL. Fairly pleasant experience. Probably helps to learn more about the international aspects of the data team.
Interview questions [1]
Question 1
Easy data structures in Python, SQL query questions
I applied online. I interviewed at Meta (New York, NY)
Interview
Prepare technical concepts, and practice previously asked questions as much as you can find online. 4 rounds in the total process. It's easy as long as you just practice a LOT.
I had Python and SQL round for 30 minutes each. The interview was for 1 hour 30 minutes for SQL and 30 mins for python coding.
Completed 5 questions each but still got rejection email the next day.
