There were 7 rounds of interviews in total:
I passed all the interviews, and the recruiter said I did pretty well (based on their internal ratings, I received 4/5 stars). I had multiple calls with recruiters throughout the process.
However, after the last HR round, the recruiter ghosted me. I followed up by email about 5 times and called once, but received no reply at all. There wasn't even a rejection email.
This unprofessionalism was a waste of time.
