Software Development Engineer Intern Interview

Anonymous Interview Candidate
Bangalore

I applied through college or university and the process took a day - interviewed at Amazon.com in September 2013.

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
