Post resume online and an Amazon recruiter contacted me. Two phone interviews. Got rejection message from the recruiter two days after the 2nd interview. Asked to write code to reverse a string and search a substr. Asked algorithm to produce power set. Did not do well on the second interview since I forgot the formula to calculate combination and slow to react to interviewer's hint to get the answer. Also did not communicate well enough as I was thinking hard. I rated the difficulty level as average because the algorithms would be easy for people freshly out of college. Asked some generak OO design questions about 1. designing a parking lot and 2. components to handle orders. Interviewers seemed to be professional and smart. Thought I did well enough to make it thru the 2nd round but... I thanked the inverviewer after the interview both times but never contacted the recruiter. Not sure if they liked that. Never showed enthusiasm at all during the interview process as I was sure Amazon is not a right place for me. I accepted the interview just to find out what their culture is. Not worth it. No regret at all.
