Amazon Software Development Engineer (SDE) interview questions

3 months after submitting my application I went through all the stages of the interview. A month later I have yet to hear back from my recruiter despite numerous follow up emails. Very unprofessional as Amazon themselves say they will strive to followup in 5 days.

first round was coding round with questions in ds and algo. Next interview round where again ds algo was asked. The company came in my college. Even though i was not selected the experience was nice.
