Amazon Software Development Engineer interview questions

I applied online after applying and declining the offer for the previous year. There were 2 (maybe 3?) online technical assessments. The first one was a debugging section that was timed, and there was also a workplace simulation. Then there was a technical phone interview.

At first they send me an online assessment It was a little bit easy then after that they schedule a phone call interview for half an hour I was asked some technical questions and also a behavioral questions then I was invited to one : one interview and they send me an email for all the preparation needed there were four interviews each one for an hour and focus on a particular technical side and also one or two behavioral questions
