    Average Interview

    Application

    I applied online. The process took 3 weeks. I interviewed at Amazon in February 2014.

    Interview

    I applied online in Jan 2014. Received an email from recruiter about setting up two phone interviews, each of 45 minute length. The recruiter was supposed to send me a follow up email about which areas the questions will cover etc. but it was sent after the first interview started.
    The interviews were back to back with 15 minute break between them.

    The questions were purely technical and only one of the interviewers asked about why I would like to work in Amazon, I think it was more to do with starting a conversation than taking any notes from my answers.

    Both interviewers for the first 10 minutes asked questions on some basic algorithms, their complexities and Maps etc.

    Interview Questions

    • The questions were something on the lines of,
      - Given a tree, output levelwise nodes (Ans: It was actually the BFS algorithm, but I didn't realize it at that time)
      - Find first unique substring (In O(n)) (Ans: Use counting sort variant)
      - Convert an array into balanced binary search tree (Ans: First sort the array, then use recursive algorithm after splitting the array at mid, and using the mid as a node)
      - From two arrays N and M find the combinations that add up to say X (Ans: I was drained by the time second interview started, so the only answer I came up with was of O(n2) complexity i.e. using two FOR loops)   Answer Question

    Application

    I applied through an employee referral. I interviewed at Amazon (Seattle, WA) in January 2014.

    Interview

    Got referred to Amazon by a relative. They got back to me a week later and I got 2 back to back 1 hour interviews. Problems were not that hard to average difficulty, but I didn't do well.

    Interview Questions

    • Given a list of numbers, in which every number occurs an even number of times except one number, which occurs an odd number of times, return the value of the odd number. Question should be done with a hash map but I used a n log n solution.   Answer Question

    Easy Interview

    Application

    I applied through college or university. The process took 2 weeks. I interviewed at Amazon in January 2014.

    Interview

    Applied mid-Jan. Got an email invitation for a phone interview one week from applying. Standard two back-to-back interviews, 45 minutes each.
    Both interviews started out with basic data structures question and moved on to coding for the last 20 minutes. Questions ranged from Queues vs Stacks, Time complexities to perform all sorts of operations on Graph structures to what data structure to use given a particular situation.
    Coding problems were easy (Merge two linked lists) but I screwed up the syntax a bit.

    Interview Questions

    • No difficult questions, really. Tricky in a way maybe, if you miss a detail, but if you are alert, you will sail through.   Answer Question
