Amazon Software Development Engineer interview questions

firstly, I get a human resource's email that tell me to join a interview for software development engineer or software development engineer Test, then I get a email that contains a link which led me to an online assessment of Amazon, after I finish online assessment , a Work Style Assessment was sent to me and after finishing it, I go to onsite group interview in Seattle

Amazon had hiring event in my town. They contacted me via LinkedIn couple of weeks (I think it was around 8 weeks) before the on-site interview was being held. First, I solved two coding challenges online and then had on-site interview. On-site interview was actually 5 different interviews - 1 hour each. There were also 5 different interviewers. At the end of each interview they had one or two questions regarding social skills and then 5 or 10 min for my questions.
