My conversation with Facebook started when recruiter send me an email, we scheduled a call where she asked about my interests and background. Surprisingly recruiter asked me a technical question, it was not hard (Fibonacci function and its optimizations), but it was unexpected. Anyway I answered her question in details (bottom up solution, top down, DP) and she replied that it's exactly what she expected to hear. Since I'm local to Bay Area I had an opportunity to have 1:1 onsite screen instead of phone screen. I choose that option and we arranged the interview in a week. Onsite screen was good, the interviewer was very nice and friendly, he was very helpful during the interview and there was an impression that we wanted to see my process of thinking. Eventually I solved the problem that was average difficulty. I started with brute force and then optimized it. In 2 days I got a call from the recruiter, she told I did well and we scheduled onsite interview. There were 5 interview for onsite: whiteboard programming -> whiteboard programming -> resume discussion with coding -> architecture discussion -> whiteboard programming. The problems were average difficulty. I was kind of slow on the first and last coding, I think it was expected to solve a couple of problems instead of one. All interviewers were very friendly and helpful, at the end all of them shared that I solved the problem correctly and in an efficient way and that it was OK that we solved only one problem. I already wanted to say that regardless the result my experience was positive, but after the interview I got a pretty bad experience. I didn't have any response or feedback for 2 weeks after the interview. I expected the rejection, but the silence in the first week gave me some hope that they are thinking about me (I was slow on the interview, but I didn't fail it completely). After the first week of silence I tried to contact me recruiter and eventually I figured out that she left Facebook and didn't move my case to anyone. I tried to contact Facebook careers page on Facebook, but it was helpless, they didn't reply to me. So, I found coordinators email (who scheduled my interview) and she finally shared the decision with me.
