    Application Details

    I applied through college or university. The process took 4 weeksinterviewed at Amazon.com in February 2014.

    Interview Details

    Applied in university career fair, a week later got an email to schedule on campus interview. Had the interview a couple weeks later, 45 minute interviews back to back with two software engineers.
    Although the email indicates you should study databases, operating systems etc., the majority of the questions are on data structures and algorithms. Lots of linked lists, hash maps, binary trees etc.
    Got acceptence email a week later.

    Interview Questions
    • There are a lot of questions that can be solved by arrays, sorting can be done in O(nlogn)... but they are looking for more than just correct answers, having an answer with a high time / space complexity won't help you.
      There was a tough question about linked lists with next and arbitrary pointers.

    Interview Details

    Amazon interviews its interns by having two, 45-minute conversations. If both you're interviewers say yes, then you're in. Otherwise, you get a third shot. You need two out of three interviewers to agree in order to hire you.

    Interview Questions
    • They asked standard data structure questions. For example, search times and design decisions.   Answer Question
    Negotiation Details
    There isn't much negotiating as an incoming intern. But the offer is very reasonable so I didn't feel the need to negotiate.
