I applied through university. The process took 3 months. I interviewed at Meta (London, England) in May 2015
Interview
After submitting my resume and answering a few questions on past projects, job preferences, etc. I had two Skype interviews on algorithmic questions. The problems posed were quite fair and had to be solved in a programming language of choice in an online editor. After that, I was invited to an on-site interview in London (expenses paid) with three more one on one interviews. Two of them were once more on coding, this time on a white board. The other one also had a small coding part but also included questions on previous projects, team behavior etc.
Recruiter call was pretty standard, first round was 2 Meta tagged LC mediums in 45 minutes. On-site was 2 coding sessions of 2 LC mediums, a system design interview and a behavioral interview with an engineering manager.

Question 1
How do you answer if someone asks how long a deliverable or project will take?
The entire process usually takes 3–8 weeks, depending on scheduling and the specific role. Coding interviews heavily emphasize common DSA topics such as arrays, strings, trees, graphs, BFS/DFS, heaps, hash maps, and dynamic programming. System design becomes increasingly important for E4+ positions.
