After the initial screening call with HR, there was one round with the hiring manager. The interview went well with positive feedback at the end. Also, the HR confirmed that he has received positive feedback from hiring manager and that there will be a subsequent round. But after weeks of wait and followups it never happened. They did not even send a follow up email for next steps or rejection.

Phone interview with HR, then 3 more phone interviews with 3 different people, and 1 interview with hiring manager. The phone interviews went well and I was excited at the feedback I was getting from 2 of them. It sounded like they really wanted me on the team.
