Amazon Non Software Development Engineer interview questions

Online application -> 1 hour phone interview (technical questions on data structures and algorithms and OOP) -> on-site interview (3x1 hour technical interviews similar to phone interview with different interviewers and 2 behavioural interviews)

Was approached by a recruiter on LinkedIn, then did an online programming test, then a phone interview. The whole processo took around 2 months. Every e-mail is sent by a different person. They provide no feedback at all in any of the steps. The phone interview is very scripted, you can easily find the possible behavioral questions online. There was also a coding assignment during the interview, it was a very simple string search problem, they ask a lot about time and space complexity.
