    Interview Details

    The interview was simple with three questions:
    1) remove duplicates in an array
    2) hash table implementation in C
    3) find max in an array

    Since it was so easy, and I had given all the answers with correct complexities. Still did not get the offer.

    I applied through college or university. The process took 3 daysinterviewed at Amazon.com in March 2013.

    Interview Details

    This was a campus recruiting event for which Amazon came to my university. It selected students from both CSE and ECE department. I am from the ECE department but was pleasantly surprised that I even received a call for interview. All the students were asked to schedule their time slots over a interviewing period of 3 days.

    Interview Questions
    • There was not a really difficult question. The first question was based on design classes. And the second one was on checking whether a binary tree is a binary search tree. One question per round. I screwed up the second question.. so did not get the offer.   Answer Question
