    Average Interview

    Application

    I applied through a recruiter. The process took 3 weeks. I interviewed at Amazon Lab126 (Sunnyvale, CA) in May 2016.

    Interview

    Recruiter reached out to me initially, had a technical phone interview with an engineer followed by an onsite. Things went smoothly and folks were friendly. Glad I got another offer as I heard this was an extremely hectic and hostile environment with high turnover rate. The behavioral questions easily gave that away.

    Interview Questions

    • Quite a few behavioral questions to test if you can handle an extremely hectic and hostile work environment   Answer Question

    Interview

    Two phone interviews. Followed by onsite interview. Prepare data structures thoroughly - heaps, trees, linkedlists. Get your string manipulations done too. They test out your problem solving technique. Besides whiteboard coding, they also asked about modeling an airport. One of the interviewers was more intent on stalling and interrupting me than listening to my solution. That was the only harrowing part of the interview.

    Average Interview

    Application

    I applied online. The process took a week. I interviewed at Amazon Lab126 in November 2015.

    Interview

    First round is a technical phone screen with a guy who is very arrogant. The guy has a strong accent. I work with ppl from all over the world (Scotland, India, Russia) very well with no problem understanding them, but I have to try hard to understand this guy's accent and beg for repeat quite a few times, and he seems a little offended. I was given a coding question to solve on an online collaborating website. I solved it quickly, but when I explain the code to him, he couldn't understand. I tried explain to him using test data to go through the code, but he kept interrupting me and saying he didn't understand. I've never felt being tired talking before in my life. Then he let me put my code in IDE and test(I wrote in java) and he would do the same thing on his end. I felt relieved honestly cause we don't need to talk for a moment. At last I think he saw my code gave the correct output, because he didn't tangle on this problem any more, but jumped to the next question, after a long silence. After two days I got the reject email.

    I applied through a recruiter. The process took a week. I interviewed at Amazon Lab126.

    Interview

    Phone interview after initial call from recruiter. Phone interview was supposed to be for 45 minutes but went on for 1 hour and 45 minutes with an hour of technical discussion. I did the interview extremely well, only to get rejected in 2 days. No idea what happened internally that caused them to not move forward with the process.
