    I applied through an employee referral – interviewed at Facebook.

    Interview

    Started with a quick phone call from a recruiter at facebook. He was very nice and polite but not technical. Questions were related to past experience but I felt as though it was more just a quick fit check before moving to a more technical interview.

    Next step was a call with a Senior Engineer. The phone call was about one hour in which the you will be quized about elementary data structures and algs.

    Application

    I applied through college or university – interviewed at Facebook (Menlo Park, CA (US)).

    Interview

    Process:
    This is for undergrad full-time software candidates in USA. Submitted resume at college career fair. Got email about on-campus interviews. At this stage, there are 3 possible outcomes: onsite invitation, a phone interview for an additional chance, or reject. I was invited to onsite interview.

    Onsite was a "University Day" that included three interviews (not four like they said in the email) before lunch and then a tour, new-hire panel, etc after lunch.

    All interviews were 45-mins length.

    Interviews themselves:
    On-campus interview: 3 coding questions. I don't remember signing any NDA at this point so, the questions were k-Nearest Points to Origin, finding a substring, and 3-sum.

    On-site interview: 3 interviews, 45 mins each. 1st interview: 2 coding questions. 2nd interview: behavioral questions (about team conflict, etc.) and a coding question. 3rd interview: 2 coding questions. Coding questions were easy and required *no knowledge* of special algorithms or data structures (such as graphs, DP, trees, etc). Recursion and strings were common.

    I did not get an offer from Facebook; however, I received offers from other companies. The interview questions themselves were considerably easier at Facebook than those asked at Google, LinkedIn, MS, Amazon, etc.

    Since the questions are not very hard, my guess is the decision is based upon fit and most importantly how *quickly* you were able to arrive at your solution and how *perfect* your code was. Make sure you focus and are confident.

    Advice: practice the easier questions and practice coding them. Also, looking at some of the other experiences on Glassdoor, it looks like a majority of the questions are re-used.

    Interview

    Referred by school mate and got the phone interview. Failed in the first round interview. No questions on resume. Just two coding questions. First one is easy. I just said minHeap solution, then the recruiter directly said next. I was stuck at the second problem and that is the reason why I failed.
