I applied through a recruiter. The process took 4 weeks. I interviewed at Meta (Tel Aviv) in Nov 2018
Interview
30 minutes recruiter screen and 1 hour technical screen, 5 SQL + 5 python, I managed to solve all python questions and 4 out of 5 SQL questions. They were super nice and I think I didn't got an offer because I was a little bit stressed.
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.
