I am from an embedded background. I applied for a Software Engineer position at Amazon (embedded domain).
Got a call from HR almost after 1 month to setup telephonic round. I practiced using Leet code for about two weeks (thanks to this platform).

Phone screen:

Interviewer introduced himself
Asked for my introduction and my major work projects.
Interview was divided into two parts as he mentioned :
  1. Work Experience and major projects discussion
  2. Behavioral Question

I think interview went very well and do not see any hiccups. My profile was almost line to line matching to the job description.

I called HR to know the status as i already had an offer and wanted to know the status of this interview. He replied the interview did not want to move forward with you.

I asked him what was the issue as i thought the interview went really well? HR told me the interviewer has not filled the feedback form properly. He did not had much info to reply.
