I applied through a recruiter. The process took 3 weeks. I interviewed at Meta (Boston, MA) in Nov 2018
Interview
First Interview : On phone - Technical : SQL (30 mins) Coding (Python, 30 mins)
4 SQL, 4 Python. Onsite coming up in few weeks.
Important to walk through your thought process while you code. Interviewer are very helpful. They will definitely give you hints, cash on them,
Prior to that, the HR provided sufficient practice material. Same, Leetcode, HackerRank.
Interview questions [1]
Question 1
SQL : Top 3 Products by sale, % using Case, Basic Having clause and one Set operator (Intersect) type question
Python : Average word length, ip-address parsing, dictionary, list of lists, flatten list of lists. ( Similar to previous interview experiences)
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.
