    Interview

    First interview went horrible. Interviewer was very unresponsive during entire phone call. Answered 2/3 questions. Third question regarding graph algorithm I was not able to solve and I believe that is what caused me to not get offer. Know your data structures and algorithms very well.

    Application

    I applied online. The process took 4+ weeks. I interviewed at Amazon.

    Interview

    I was scheduled for two back-to-back 45 minute long phone interviews. Both of the interviewers were quite pleasant, and they dove into technical problems immediately. Due to technical reasons (I really chose the wrong place to sit-- the call dropped several times and the internet stopped working), the first call was rescheduled for a week later. Both interviewers used an online collaborative coding website for the technical questions instead of asking me to write on paper. The technical questions were nothing too unexpected:
    - Find the intersection of two arrays of integers (the elements that are in both)
    - Given a set of integers, produce its power set (the set of all subsets of the original set)
    - Reverse a linked list
    - Given a string, what characters are in it?
    Only one interviewer asked me about my resume ("tell me about a technical challenge on a project you've worked on").

    Interview

    Just had my first round of phone screening interview. First interviewer asked programming related questions and asked me to code. The second one basically asked higher level and open ended technical questions. Both used an online code typing and sharing tool.

    Application

    I applied through college or university. The process took 1 day. I interviewed at Amazon.

    Interview

    Very nice recruiters, gave me a lot of helpful hints to solve their questions. Asked to write a function that prints the sum of 2 numbers that are represented by linked list. Wasn't too bad, but I made a few errors.

    Interview Questions

    • Questions about how subtypes work. I wasn't expecting that, and was pretty rusty on them.   Answer Question

    Application

    I applied online. The process took 2+ months. I interviewed at Amazon.

    Interview

    I submitted my resume through the website about 2 months before they contacted me. They sent me back an email at the end of February regarding a phone interview. The phone interview was two calls back-to-back.

    The first call was not really technical. The interviewer asked about projects and my background, and he was very nice. We did one coding exercise over CollabEdit. He was very interested in how I thought about the problem, so make sure to articulate what you're thinking about when you are given a problem and how you're thinking about solving it. The question was how to implement the division function without using the division operator.

    The second call was a technical interview. The question was find the element in an array that appears an odd number of times. All elements are guaranteed to appear an even number of times, except one, which will appear an odd number of times. He asked a lot about the space and time complexity of the solutions that you provide, so make sure you understand those concepts and can apply them to your solution.

    I did not receive an offer, but they replied back within a week.
