I applied through a recruiter. I interviewed at Meta in May 2017
Interview
Recruiter reached out to me on LinkedIn. The technical interviews were setup a month later consisting of SQL and Python coding questions over the phone using Coderpad. The questions asked were as expected from the other reviews here, although I did not do so well because I wasn't used to Coderpad. For the SQL portion they really want you to figure out how to write it in one query instead of using subqueries or joins.
Interview questions [1]
Question 1
What are the states with a total of x amount of square feet?
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.
