Meta Developer interview questions

1st round HR screening 2nd round coding online 3rd round coding online The 1st and 2nd rounds are great. However, the 3rd one is terrible since the guy on the other end of phone is keeping silent and provided little feedback during the whole process. Basically I think they are more interested in find the people who can do tricky programs in a very short period of time while keeping solid code and clean coding style. The HR is very fast in turnaround, though the final decision is kind of be kept back for a while, but if you ask they will let you know. Anyway, this is the first company I got interview so maybe it is just too difficult for a rookie interviewee. BTW, I though Chinese engineers tend to be more silent in interview, which is sort of "rude" to the interviewee since there is not much conversation in such case.

I was contacted by the Facebook recruiter saying I need to solve one of the puzzle from the Facebook puzzles to start the interview process. I had solved one problem and then recruiter scheduled my phone interview. The interview was good. The guy at the other end was nice and smart. The interview last for around 1 hr. It start by asking me about myself. He asked me about my choice between three platforms (linux kernel, MySql, JAVA script). I had chosen Mysql and he asked me why did I choose MySql. Other questions are described below. I got response from the recruiter that they would like to keep me on hold, as they are finding difficulty in judging with large number of candidates. I answered all questions correctly (I feel) except my written code (took around 10 to 15 mins) for the problem had one bug which he had noticed correctly and told me to resolve it. After resolving it he gave me the green signal. One of the big problem (I guess one of the main factor in the interview) I faced that as I am OK with English, I was finding difficulty in understanding his accent. So many times the interviewer had to repeat his questions. Lastly he asked me if I have any questions for them. I asked one question. This is how end my phone interview with Facebook.
