Amazon Software Engineer interview questions

2 round 1st round is oa with 2 questions didn’t pass all the case for the 2nd question, they are both graph related. Then there’s a 20min behavior question. Forgot if there was a time limit for 2nd half. Heard back from them about one and half month later 2nd round got interviewed with a sinner engineer who mentioned he just joined Amazon a month ago. Asked me a question on how to use Stack, to put on difficulty it was probably easy easy. Have no idea why they decided to reject me.

Took an initial call and they were friendly. Asked a few questions about my background and described all the teams that were open. Decided not to continue as their interview process is very long now.
