    Software Engineer Interview

    Anonymous Interview Candidate in Menlo Park, CA
    Anonymous Interview Candidate in Menlo Park, CA
    Application Details

    I applied through college or university – interviewed at Facebook.

    Interview Details

    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.

    Intern Interview

    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)

    Software Engineer, Interview

    Anonymous Interview Candidate
    Anonymous Interview Candidate
    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.

    Software Engineer Interview

    Anonymous Interview Candidate
    Anonymous Interview Candidate
    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

    Interview Details

    I first got a phone call where they vetted me over the phone. That went well, so they brought me in for an in-person interview. I signed an NDA, so I can't go into too much detail. I will say that they keep you on your toes throughout the process, so keep your thinking cap on.

    Software Engineer Interview

    Anonymous Interview Candidate in New York, NY
    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).

    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.
