I applied online. The process took 3 weeks. I interviewed at Meta in Dec 2015
Interview
A phone interview. A recruiter was very nice. At first he introduced himself. And he asked me please introduce yourself. And then he gave me a question. It seemed very simple but I should optimize time complexity of the question. I tried to use divide and conquer. I thought I can solve it by using while statement because I don't want to use recursion. It worked well but time complexity still depended on length of output. I regret that I should use recursion. Although I didn't get offer, it was good experience. Additionally, an interview process of Facebook was really fast and clear. I like it.

Question 1
The question was related to recursion and binary search.
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.
