I applied through a recruiter. The process took 3 weeks. I interviewed at Meta in Aug 2017
Interview
HR found my profile in Linked in and called up for a discussion. There was the usual background discussion and very simple sql questions. Then they scheduled a phone screen for a sql and python interview. They gave some prep materials as well. In the phone screen, it was all coding. I had assumed it would be a combination of sql and python but it wasnt. I didnt move past this stage.
Interview questions [1]
Question 1
Dot Product with Sparse Vectors, Dot product of sparse vectors stored as hashmaps
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.
