I applied online. I interviewed at Meta (Menlo Park, CA) in Apr 2017
Interview
It was a great experience. The interviewer called me asking for some introductory information and then I was moved forward to the phone interviews. Two rounds each of 45 minutes with one being on SQL and the other on Python.
Then I moved to onsite where there were three rounds each of which was scenario based and had to design and develop Data models. It was fun
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.
