I applied online and the process took 4 weeks - interviewed at Amazon.com in March 2014.

Interview Details I applied online through their website, and was contacted a few weeks after asking for an interview time. There were two interviews of about 45 minutes each, with engineers from different teams. They called at the exact time scheduled and were extremely polite.

The interviews themselves consisted of the following:
1) A few minutes talking about myself, and some of the items on my resume.
2) Questions about how I would go about solving problems relating to data structures and algorithms.
- One of the problems was "How would you implement a stack within a queue?"
3) A programming problem where they would have a pre-written question and they would watch as I solved it.

Unfortunately, I was unprepared for the interview, and thus was not able to answer the questions quickly and efficiently. They really want to know that you know the efficiency of the things you write.

Interview Question – Reverse a linked list (sorting doesn't matter)   Answer Question
