    Intern Interview

    Anonymous Interview Candidate
    Anonymous Interview Candidate
    Application Details

    I applied online - interviewed at Facebook in June 2014.

    Interview Details

    The process was as expected. First I submitted my resume, then once that was accepted I had to take an online Hackerrank test.

    After passing that, then I received a phone call giving me more details about what to expect over the next stages.

    Then was the phone interview, where I had to use collabedit to type my answers to the problem given. I was also asked if I had any questions. The interviewer was really friendly and made efforts to help when I seemed stuck.

    Interview Questions
    • Letters are represented by numbers, e.g.
      A = 1
      B = 2
      ...
      J = 10
      K = 11
      etc.

      Given a number (e.g. 113), how many different combinations of letters could this be converted to?

    one hackerrank, three technical interview.
    the hackerrank question is fairly straightforward but easiest to do in higher level language.
    technical interviews were okay, but not hint-ful or anything. made a stupid mistake in the last one and it cost me a lot :(

    User Operations Analyst Interview

    Anonymous Interview Candidate in San Francisco, CA (US)
    Application Details

    I applied online. The process took 3+ weeks - interviewed at Facebook in January 2014.

    Interview Details

    I applied online through Facebook page, and they contacted me right immediately like on that day which was scary for me. I guess they embody truly the culture of moving fast. I got an e-mail with to complete some online test with 13 questions and they were on:
    13 questions:
    9 Analytical Multiple Choice Questions – focusing on sets, trend analysis, calculus, stats, etc.
    1 open ended basic SQL question.
    1 open ended normalization question.
    1 Multiple Choice English language comprehension question.
    1 open ended language question (this part should be 200 – 300 words).
    The entire online assessment test was conducted through hackerrank.com and it was for 90 min.
    Personally I did not go and complete the Quiz within couple of day. I did take my time to prepare and I was right. It is a difficult test. I did use apps like the impossible interview and the aptitude interview from iTunes app store to prepare. They were a help.

    Interview Questions
    • The most difficult or unexpected thing was that they contact you right immediately leaving you no time to prepare, so before you apply take you're time to prepare and they apply. other than that this question was pretty difficult:

      An analyst at Facebook is conducting a satisfaction survey sampling from a list of 10,000 new users. The list includes 2,500 French users, 2,500 German users, 2,500 Italian users, and 2,500 Portuguese users. The analyst select a sample of 400 users, by randomly sampling 100 users of each country. is this an example of a simple random sample?

    Software Engineer Interview

    Anonymous Interview Candidate  in  Menlo Park, CA (US)
    Anonymous Interview Candidate in Menlo Park, CA (US)
    Application Details

    I applied through a recruiter. The process took 4+ weeks - interviewed at Facebook in July 2014.

    Interview Details

    I was hiring specifically for an iOS position. The recruiters start with Obj-C 5 multiple choice questions, which required some surprising depth. I won't get into specifics, but take time to understand memory management (even with arc), blocks, addresses and pointers.

    After was a phone interview which mostly involved a collaborative coding question. The questions asked here were very typical algorithmic questions, the answers usually involved a hash to cache meta values to increase performance.

    Protip: Be familiar with NSSet and NSOrderedSet. These data structures are more performant than NSArrays for some operations, and I found myself using them in almost every answer.

    Then you have an onsite visit, with 4 additional interviews: 2 coding, 1 design, and 1 "culture fit" which, for me, was really another coding interview.

    Your recruiter will contact during the next week or two afterwards to give you updates on your status. I believe there are three different meetings where your interviewing notes are reviewed and given consideration.

    I went back and forth once between a competing company and received higher offers each time. Ask your recruiter for honest assessments of your interviews - if you did well FB will be much more willing to "one up" the competition.

    Content Strategist Interview

    Anonymous Interview Candidate
    Anonymous Interview Candidate
    Application Details

    I applied through a recruiter. The process took 4+ weeks - interviewed at Facebook in May 2013.

    Interview Details

    I was contacted through LinkedIn by a recruiter at Facebook. After a phone screen, the recruiter recommended that we move to the next phase and asked me to complete a written exercise that involved identifying content strategy opportunities on Facebook.

    About a week later I received a response from the recruiter informing me that they would not be moving forward with my candidacy.

    I was assured that my work wouldn't be used on Facebook. In the time since these initial communications, Facebook has just released a feature which is strikingly similar to what I had described in the exercise I submitted. Of course, this could be a total coincidence. but nonetheless, it would have been useful to get some kind of substantive feedback (or at least an interview) considering the time it took to complete this exercise.
