Amazon Intern interview questions

It was a online test followed by a round of two interviews. The online test is really simple, with easy coding questions. My interview went really well, was really expecting a offer though. The process in completely unpredictable. In phone rounds I was asked questions about trees, algorithms, data structures, time complexity. It started with discussing my previous project work.

After an online numerical test I had 3 interviews, the first round was one phone interview, followed by another 2 phone interviews back to back. The process was great, the interviewers were really friendly members of the team (not HR recruiters) and asked a lot of STAR questions based on their leadership principles, so it's important to think of examples where you've shown each of their leadership principles through your own work. Each interview was a similar format, overall it took about 3 weeks from first interview to an offer.
