    Interview Details

    First I got a phone interview, where I was asked a few background questions like previous experience. After this, I received an email for an on-site interview. After a brief tour of the campus in Palo Alto, I was brought to a room where a Senior Software Engineer interviewed me. I was asked a number of simple questions, and then one complex coding question.

    I applied through a recruiter. The process took 2 weeksinterviewed at Facebook.

    Interview Details

    Met the recruiter at a career fair, dropped off my resume, and was contacted for an on campus tech interview. Interviewed with a Russian guy with a really heavy accent and I could NOT understand much of what he was saying. He also got impatient with me and basically wrote the answer on the board after 1-2 minutes of watching me struggle. Not a very helpful or nurturing interviewer.

    I was contacted by a recruiter after the Facebook NY Hackathon. She set up one technical phone interview, if I passed there would be another technical phone interview. After those two they would make a hiring decision.

    I applied through an employee referral. The process took a weekinterviewed at Facebook in October 2014.

    Interview Details

    I applied through an employee referral. I soon got a 45 minute on-campus interview with an engineer. We jumped right in to technical questions. I was asked one whiteboard coding question (with some follow up questions on ways to break the algorithm, runtime, edge cases), and another easy whiteboard coding question (the fact that it was easier was not a good sign).

    Interview Questions
    • The question I got was not a difficult question, but whiteboarding the code was where I messed up. It was: how do you find the lowest common ancestor of two nodes in a binary tree.   View Answers (2)

    I applied through a recruiter. The process took a weekinterviewed at Facebook in October 2014.

    Interview Details

    Contacted by recruiter via LinkedIn. Phone interview set up one week after contact.
    Interviewer contacts you on day of interview and send you a link for an online document editor.
    Interview lasted 45 mins.
    The interviewer started off by asking me what my most interesting project is that I have worked on. This took less than 5 mins.
    Then the interviewer gives you the rest of the time to solve a programming problem.
    The last 5 mins or the remaining time you can ask the interviewer questions.

    The question was fair. Not a brain teaser. Interviewer was very nice and helpful.

    I applied online. The process took 2 weeksinterviewed at Facebook in September 2014.

    Interview Details

    Applied online, recruiter reached out to me and set up a phone interview. The interviewer over the phone was slightly ambiguous and lead me in the wrong directions. However, I think the goal was to really analyze your thinking process.
