    Software Engineer Interview

    Interview Details

    The interview is quite intense, including several rounds of coding, design, and culture interviews. Some interviewers can be annoying. One person showed great disbelief when I mistook one of their great technologies by something else. Another guy was pounding me about why I wanted to be an engineer. And in one coding interview, the guy was looking at his phone while I was doing whiteboard coding. He apparently has less knowledge about the interview subject, but he did manage to find a small bug and failed me. I am glad that they did --- how can I work with such assholes? Compared to other places I went, Facebook has the highest concentration of mediocre quality, high ego engineers. An unpleasant place for engineers!

    I applied through college or university. The process took a dayinterviewed at Facebook.

    Interview Details

    Implement an asked simple function in an empty paper. Each type of variables (ex. int, double) and using conditional / iterative statement had to be chosen carefully to avoid a single mistake.
    Then typical personal questions came after the code interview.

    Software Engineer, Interview

    Interview Details

    The first interview was at my University. It was your typical 45 minute face-to-face whiteboard coding style interview. During the first five minutes, my interviewer introduced himself and asked me questions about myself. Be prepared to talk about yourself and your resume. The next 35 minutes were spent entirely on 1 question. After arriving at a naive solution, I fined-tuned and optimized my code. The last 5 minutes were reserved for any questions I had.

    I passed the first interview, and went on to the second interview. The flew me down to HQ. This interview went horribly. The question was more difficult than the first interview, and my interviewer's accent made him difficult to understand. After the interview, I toured Facebook's campus and had lunch, etc.

    A phone interview, simply ask some question about resume and then ask coding question. They sent a link to you and use the link to coding. Just one question, the question is typed by them in the link.

    Application Details

    I applied through an employee referral. The process took 1+ weekinterviewed at Facebook.

    Interview Details

    I was referred by a friend.

    Whole process took a week in a half - due to a pending deadline on my part.

    I had a phone interview and was then invited onsite at the end of the week. The onsite interview was composed of 3 interviews. They were typical questions of any other technical interview questions - although slightly more tree-heavy than other companies.

    On Monday I was contacted asking to provide references. I thought I had it in the bag because of this but Tuesday evening I was rejected.

    I know that they were strong and wouldn't cause my rejection. So I guess references are asked for before the onsite interviews are processed?

    Product Manager Interview

    Application Details

    I applied through an employee referral – interviewed at Facebook in November 2014.

    Interview Details

    I had applied for a Rotational Product Manager position through a employee referral. The recruiter was pretty quick in getting back to me. The first call was with the recruiter and the questions were pretty basic - tell me something about yourself, why Facebook etc. She also asked me which products in Facebook would I like to work on and if there is anything I would like to change in any of the products. At the end of the call she said she would set up a phone interview and told me that the interview would be "Product Sense" interview. More of how to design a product and what choices I would make in the process.
    The phone interview was 45 mins. The first 10 mins was more of introductions. The question was - how would you improve Facebook birthdays, and the follow up questions included what metrics would you use to measure the successful launch of your product, how would you prioritize your features.

    Recruiter Interview

    Application Details

    I applied through other source. The process took 5+ weeksinterviewed at Facebook.

    Interview Details

    Not a great experience. While I met some nice people and for the most part it was pleasant overall, it was all for not when I got to my last interview and it was very unpleasant. In all fairness, I do terrible in interviews and I probably wasn't answering questions well.

    Over a 5 and a half week period I had 5 interviews (2 were rescheduled), 2 phone and 3 face-to-face. I was initially contacted about one position, but by the 3rd interview I was told that was not the position and it was a different one… For my 2nd phone interview it was rescheduled twice as they were never confirmed and they just phoned out of the blue. It seems, from my experience at least, the left-hand doesn't know what the right-hand is doing. Too many unnecessary moving parts for my liking, recruiter, administrator, coordinator… Much easier if someone picks up the phone and confirms a day and time?

    Walking into the building it definitely looks/feels like you have to drink the kool-aid before they let you pass! I fail already... I'm a square peg and don't fit in a round hole.

    Escorted everywhere, including the bathrooms! Which I kind of get, but a little over the top for my liking, especially waiting outside the bathroom door for me. Literally. Walking through the work spaces I don't get how work can get done in an efficient manner with staff sitting on top of one another. Oh yeah, don't even think about opening your personal laptop, which I made the mistake of pulling out and trying to power up in my interview… That was met with instant resistance and an accusatory what are you doing? There are no laptops! Didn't they go over that with you at the front desk? Nope.

    Software Engineer Interview

    Anonymous Interview Candidate in Seattle, WA
    Anonymous Interview Candidate in Seattle, WA
    Application Details

    I applied through a recruiter. The process took a dayinterviewed at Facebook in November 2014.

    Interview Details

    1 Behavior/Past experience
    2 Ninja
    3 Lunch (not rated)
    4 Design
    5 Ninja

    The behavior interview is about 1 hour, just talking about your past and current experience and projects you have done, plus a 15 mins coding test.

    first Ninja is an opening question, essentially creating your own question based on a scenario and do some coding. My experience was really good so you have the flexibility to design questions you are familiar with.

    Lunch was chat with a senior team lead, relax and get to know what you want to know.

    Design was easy for me, since I have done a similar system at my current job.

    the last ninja really sucked, the question is about a really unconventional event processing model using "pulling" instead of standard "push" model (like Storm), and the interviewer does not talk much and was not happy when I proposed the much simpler and intuitive push model. I failed on this one.

    Interview Questions
    • The second ninja (coding) test was about event processing system using pulling model, which literally no one in the industry is using.   View Answers (2)
