    Difficult Interview

    Application

    I applied through a recruiter. The process took 4+ weeks. I interviewed at Facebook in March 2018.

    Interview

    I was contacted by a recruiter through Linked in. She spoke with me about my work history for a few minutes and then asked me some basic android questions. Then she told me that they would like to schedule me for a phone interview with a developer.

    I was scheduled for an interview 20 days from that date.

    My phone interviewer was nice, but his speech was hard to understand. He talked with me for 5 minutes or so about my work history and then jumped into a code question. The coding question was about adding binary numbers. He provided me with two binary strings to add, and when I added them and got the result he was looking for, he told me that he wanted me to add them a different way. He wanted me to write a for loop to iterate through the binary strings and then add the two strings which would ultimately give the same result.

    We ran out of time, and he told me that I should study more and try again later. I left the interview confused, and a bit disgruntled with the process.

    Difficult Interview

    Application

    I applied through a recruiter. The process took 2+ months. I interviewed at Facebook (Menlo Park, CA) in December 2017.

    Interview

    I was contacted by a recruiter and setup an initial HR phone interview. After a few days scheduled an online collaborative coding interview. Once you passed that you'll be invited for an onsite interview. 4 interviews in total, 1 behavioral, 1 system design, and 2 coding questions. I think I performed well enough for all the interviews. I was able to provide solutions for all of the coding problems.

    The result for the interview process took more than a month. At first they said that the results would be given after a week. Recruiters does not even reply properly to follow ups. Then I got the email that I was rejected. Very bad experience on the hiring process.

    I applied through a recruiter. I interviewed at Facebook (Menlo Park, CA) in February 2017.

    Interview

    I was contacted by a recruiter to apply at Facebook for a job at their HQ in Menlo Park. I took the opportunity and did the phone interview. This interview was fairly easy and well structured. I then was invited out to Melo Park for an on site interview. The whole experience was good overall. Facebook paid for my travel and accomodations and food and everything else. The interviews were extremely difficult however and there were a total of 5 interviews, each 45ish minutes long. It was a long day to say the least but overall, my experience was good.

    Interview Questions

    • I cant really give out the questions I was asked, however, I can say I was asked 6 or 7 different coding questions, ranging in difficulty. However, they were all fairly difficult   4 Answers

    Easy Interview

    Application

    I applied through a recruiter. I interviewed at Facebook (New York, NY) in November 2016.

    Interview

    This was online interview. At first interview was scheduled on 00:00 because manager never checked, where I live. After my request it was shifted to 22:30. Unfortunately interviewer could not call me via Skype. He blame that I have outdated Skype version and should check software. This is strange, because as freelancer I use this tool every day and never had problems before.
    Interview was re-scheduled. Second interviewer could not use Skype as well, he told me that I'm offline. Strange, because I wrote him a message via Skype chat :) So we had to use phone and this was not comfortable.
    Coding assignment was really easy, though interviewer was not able to describe it clear enough from the very beginning.
    Every candidate could ask question at the end of interview. I wanted to know, if they use reactive approach in developing. Unfortunately my interviewer didn't hear neither about RxJava or about Java 8 streams API at all. You are not obligated to use this in your work, but these are things you could know about from Android Weekly at least :)
