Recruiter reached out through LinkedIn. I was excited about the opportunity though never thought Facebook for employment. Explained me about the interview process, saying first round of programming interview 30 mins Python & 30 mins SQL and then the onsite. Gave documents on what to prepare for the interview and asked me go through glassdoor for people's experience. The call itself was kinda of motivating for me to perform well. I was totally motivated and my interview was scheduled after two weeks. I flunked in First round. Prepared very hard (daily 2-4 hrs) but still some how managed to screw up in the interview. Still wondering what I was thinking when I gave the interview because in different setting I would answered it easily. I desperately wanted to clear first round and get to 2nd my bad did not do well. The interviewer was cool he was helping but you stay in control by taking time understand the question and answer. I am 11yrs exp, not sure if want to try again. My suggestion: Just prepare only what has been shared with you by the HR that's good enough Try giving mock test with time, I think this is VERY important (which I did not) questions are only from what you see here (at least for me) use monitor if you can when you give exam, since coderpad uses only half of your screen as editor I felt it's difficult with it (at hindsight). I was rushing to answer and chose wrong solution for first question and screwed it up from then on Now I realize it was simple question I over complicated STAY COOL
