Software Development Engineer I Intern Interview

Software Development Engineer I Intern
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.
