Application

I applied through an employee referral. The process took 2+ weeksinterviewed at Amazon.com in March 2014.

Interview

Got the interview from AWS team. 2 back-to-back 45 mins interview.
First interviewer(an indian engineer with terrible accent) asked me a classical Top K question, gave him a solution literally in a minute. However the solution needs a max-heap, commonly just use its api but this time he asked me to implement all, got quite unexpected here, it took me almost 30 mins to finish it. At last I asked question about openstack, unexpectedly he didn't know a thing about it.
Second round was about string anagrams, still gave him a solution very fast(hash table, O(n) time and O(1) space), it is the best solution. After this talked about my current project, I guess this is where I blew the intern opportunity cause I said it is totally boring :-/ .
Two interviewers were not nice, sometimes felt quite unpleasant. The HR really didn't respond any of my question and email, and I was told no offer a week later.

    Interview

    Interviewed on campus. First guy was very unprofessional. Was laughing half the time I was answering his questions. He at one time made a snide remark directly at me, I almost just walked out the room. I first asked him if he was comfortable with the language I chose, but I had to constantly stop and explain to him the simplest syntax and functions.

    Second guy was very professional. Straight and direct, seemed very robotic.

    Very disappointed with the interview process. Do not see myself working in this type of environment.

    Application

    I applied online. The process took 2 weeksinterviewed at Amazon.com.

    Interview

    The recruiter first sent an e-mail to arrange a time slot for the interview at about 6 days prior to the interview date. The interview was a back-to-back interview, each of which is 45 minutes. The interviewer all asked about technical questions, no personal question. The last 5 minutes of the interview were left for me to ask questions about the company.

    Interview Questions

    • The most unexpected question for me was about networking:
      Given two IP addresses and one subnet mask as input (All are string data type), write a function to determine whether the two IP addresses are in the same subnet.
