I applied online. The process took 3 months. I interviewed at Meta (Londres, Inglaterra) in Nov 2020
Interview
Lots of technical questions. Their interviewer had a poor internet connection which made communication very difficult. Interview lasted one hour. Difficult questions asked about languages and information on my CV. Leetcode preparation very useful
I applied through a recruiter. I interviewed at Meta
Interview
Interview process was very organized. I was contacted by a recruiter and I did 3 rounds of interviews. Cannot run code during the interview because the platform doesn't allow it.
Applied via referral. After doing a CodeSignal test, I was rejected at phone screen (even thought I did pretty well). The questions I were asked were pretty atypical, and you had to convert a real-world problem into a LC problem (like those questions where the LC problem is hidden under a weird analogy/story)
Interview questions [1]
Question 1
Given a database of userIds mapped to lists of names, group the names of people who have duplicate accounts (this is a graph problem, lol)
