Amazon Junior Software Developer interview questions

I went through one phone interview and then was invited to an on-site interview. Phone interview had some question to do with regex and basic methods. On-site consisted of 4-45 minute interviews back to back.

I applied online and was emailed back about a potential position in the company. It was two technical phone interviews. Each was had two questions the first was to implement a simple algorithm and the second pertained to a data structure like linked list or a BST.
