There was in total of 4 round of interview. First was a screening round which revolved mostly about your background and how you dealt with some situations. Second round was giving a presentation on one of their architecture. Third round on one on one interview and Final was HR round.

I had what I thought was a great interview with a woman from HR. She was having some computer and phone problems which was no issue but she had to call me back a couple of times after the call kept dropping. She said I was referred by the hiring manager who saw my resume and wanted to schedule another interview with him for the following week. I agreed and she promised she would call me back on that Friday to schedule. I never heard back from her. I sent emails to her and was completely ghosted.
