I applied online. The process took 3 weeks. I interviewed at Meta (London, England) in Oct 2021
Interview
Pretty standard tech interview: introduction, 2 programming questions, questions from candidate side. There weren't many follow-ups, and it seemed that the interviewer was in a bit of a hurry. I was able to solve both tasks, but I was probably expected to come up with a better complexity class for one of the problems.
There were an excessive amount of rounds with a high difficulty of questions for a new grad role. Everyone I spoke too was very friendly though! Study hard and you may be okay.
Asked me two leetcode hard style questions and I knew it was over for me. Interviewer was nice and tried to guide me along the right path but the question just wasnt clicking with me.
2 tech, 1 behavioral
Tech were basic LC questions mostly from Meta tagged
Behavioral was also standard tell me about a time questions and deep dive into a project. A tech person was taking my behavioral, so went deep into why I used that tech and similar questions
