Interview Details It was a on-campus PI. There were 3 rounds. One coding round and 2 PI's.

Interview Question – There was as such no hard question for me. But unfortunately i was not prepared for this interview. Frankly this was my first ever interview. So yes i was bit nervous and i didn't knew about the tips and tricks for cracking the interview at that time. I was asked the following 2 questions:

1. given a tree, do the level order traversal of the tree. Explain the logic and write it's proper code not pseudo-code.

2 given a link list, Reverse a Linked List in groups of given size. write it's code.

I applied through college or university and the process took 2 days - interviewed at Amazon.com in September 2012.

Interview Details On-campus interviews for the post of intern at Amazon India.
Started with a combined technical/aptitude online test. Followed by a paper-coding round where the selected students were supposed to code two algorithms on paper.
Selected students were interviewed by the recruiters. Some of the recruiters were quite unprofessional and themselves lacked knowledge regarding some basic algorithm questions. I personally know some students who suffered because they submitted an optimal solution and suffered because the recruiter failed to understand it. That's what happens in paper-coding.

Interview Question – Zig-zag traversal in a BST. I know it's a standard question but I wasn't aware of it and couldn't come up with a good enough answer in the interview round.   View Answer

Seattle, WA (US)

I applied through college or university and the process took 1 week - interviewed at Amazon.com in December 2013.

Interview Details Interviewed through university recruitment program. There were 2 back to back 45 min. phone interviews with 10 min gap between them. Got a call exactly at the scheduled time and ended it exactly after 45 min are over.

Interview Question – Question were not the difficult ones, but the sub-questions asked on them were tricky.
1st interview question: It was scenario based coding question. Asked to code it in whatever language you want. The question was; you are getting number of orders daily, code a program which will minimize the time right from processing to packing and till warehouse shipment. It was something related to Pythagoras theorem. I coded it with some time left and then was asked to optimize it considering time and space complexity.

2nd Interview: There was not a single question. It was regarding hash tables, sorting and searching, picklists and their time n space complexities. Tried to answer them.

Interview Details Got an email from a recruiter about 5 months after applying online asking to schedule two 45 minute phone interviews. They were right after each other and both of the interviewers were really nice. The recruiter was REALLY bad at getting back to me though so I couldn't reschedule my interviews in time.
