I applied through a recruiter. The process took 2 weeks. I interviewed at Meta in Jan 2018
Interview
A recruiter from Facebook contacted me on LinkedIn. I immediately said yes even though I was not looking for the job. :p
Recruiter set up a 30min call with me to understand my profile and to see if I'm a good fit for the position. I was asked few general questions about my previous work experience and technical skills followed by surprise 5min technical Q&A on Python and SQL.
Later a telephonic interview was scheduled to test SQL and coding skills. The same recruiter provided me all the required guidelines and study/reference material to prepare for the interview.
Interview questions [2]
Question 1
SQL questions based on JOINS, SUBQUERY, AGGREGATE functions and GROUP BY.
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.
