    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.

    Application Details

    I applied through college or university – interviewed at Facebook in December 2014.

    Interview Details

    I was contacted after giving my resume at a job fair. I had one phone interview with an engineer which had a fairly straightforward interview problem to solve on an online coding website. Then I was invited to interview at one of their larger offices (I chose Seattle), I was flown out and interviewed on a day that 13 other people were interviewing as well. That day I got breakfast and lunch at the company cafeteria, and had interviews with 3 engineers. One asked me how I would implement, create and solve a maze. One asked me to code a translation from base 26 to decimal.

    Interview Questions
    • I was asked how I would implement, in OO code, a maze. Then, given that implementation, to design an algorithm to solve that maze. Then, how would I create a random maze from scratch with an algorithm.   View Answer

    Application Details

    I applied through an employee referral. The process took 2+ monthsinterviewed at Facebook in December 2014.

    Interview Details

    I was referred by a former colleague who works here. I went through 5 rounds in this order: HR Screen, Hiring Manager Call, Conference Call/Group Phone Interview, On-Site, Final Call (Hiring Manager). All interviewers were incredibly professional and excited to speak with me. I interviewed with 4 people on-site, each one at a time for a half hour. Interviews were all very thorough and challenging, but conversational and encouraging. There were a number of case studies mixed in with behavioural questions.

    Application Details

    I applied through college or university – interviewed at Facebook.

    Interview Details

    The interview process consisted of a 45 min interview with one of the dev on campus. It was a technical interview with focus on data structures like tree and algos related to the same. I was asked to print all the nodes of a tree in order. Basically an implementation of BFS and then was asked to print the tree as it appears with correct new line characters making it appear as a tree and then further was asked to modify the logic such that the nodes are indented to make it look exactly like tree(we see in all the DS books)

    Application Details

    I applied through an employee referral. The process took 4+ weeksinterviewed at Facebook.

    Interview Details

    I got the opportunity through internal referral.

    I passed an technical phone screening and was invited to an on-site. I had 5 interviews in total. Two coding, two system design, one with manager (on PhD research + a quick coding exercise).

    The technical questions were not too difficult, but I was unprepared for the system design problems. One of the interviewers kept walking around in the room and was really distracting and annoying. I couldn't focus on solving the problem and didn't do well in that session.

    The interviewing schedule was not the best. I was scheduled to have lunch at 2pm PST, but considering I'm from a couple time zones east of PST, I was already way too hungry to have lunch at that time. Perhaps a low blood sugar level also contributed to my impaired thinking abilities.

    Interview Questions
    • Signed NDA. Distributed system design problems were out of my expectation as I do not claim any experience in that area nor was I interviewing with any positions related to that area.   Answer Question

    Software Engineer Interview

    Anonymous Interview Candidate in New York, NY
    Application Details

    I applied through a recruiter – interviewed at Facebook in December 2014.

    Interview Details

    the hiring process was extremely efficient. they move as fast as you need.
    i got responses from the recruiter in minutes and two hours after the interview i got the results.
    the office looks nice and the people there also.
    it looked too young to my taste. didn't see there anyone older (over 45) with experience but this was only a quick look.
    i got a problem that i can solve in 20 min with my laptop, but wen you need to code it on a whiteboard it's a different skill i don't have.
    even though your concept is right - they look for potential bugs on your code so make sure you write carefully (i don't).

    Interview Details

    Met Facebook engineers who referred me to the recruiter. The recruiter contacted me three weeks after I met the engineers. Set up round 1 phone screen within the next 2 weeks of our first email exchange. Facebook does move pretty fast with the recruiting process. The recruiter contacted me again about 2 days after round 1 interview to set up round 2. Round 2 was about 3 weeks after round 1.
