    Application

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

    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.

    I applied through an employee referral. The process took 2 weeksinterviewed at Facebook.

    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.

    I applied through an employee referral – interviewed at Facebook.

    Interview

    I applied through employee referral. I got an email from a recruiter with a questionnaire asking about my experience, why facebook, etc. Next step was a phone interview. The interviewer was very nice and helpful. The interview question was not difficult. I gave an optimal solution with some help, also finished coding in time. I don't know what they don't like about the interview, but probably I was not very fast coding and testing the code. I got an email after a few hours that they do not want to move forward.

    Interview

    I applied online through their website. I was contacted after one week and scheduled an interview for the following week. They flew me out and although the interview only lasted 4 hours, I was in California for the weekend. Great experience. Wonderful company. Although I did not get an offer, I will definitely apply again.

    I applied through a recruiter. The process took a weekinterviewed at Facebook (Seattle, WA).

    Interview

    Onsite tech screen followed by 4 1:1 rounds. Three of the technical rounds were on coding questions and one of them had a design problem. Most of the technical problems were easy but I didn't code well probably because I didn't take enough time to practice whiteboard coding. The design round had an interesting problem. I'll probably appear in this once more in a year. All interviewers were good and well-behaved. The process was smooth as well. The recruiter communicated my area of weakness (coding) and I concur with what they found.
