The hiring process was pretty tough. I had to prepare well in data-structures and algorithms to pass the interview. The interview consisted of 3 phone screens and 2 video-conference interview with 6 people (in total). They asked a questions about linked-lists, BST, data-structure design, algorithms and various technical scenarios. The phone screens took 1 hour each. Usually, they do 2 phone screens and fly-over the candidate for 1:1 interview. But since I was an international candidate they had to arrange for a 3rd phone screen. After all the phone screens they decided it was easier to do a video conference and arranged that in a local Amazon development center. The video conference took 1 hour each and spanned over two days. After a week or so, I received an email saying I was selected and they would like to extend an offer. I accepted the offer.
