1. I received a call from the recruiter. She asked me about my experience and interests.
2. They sent me a code challenge to solve.
3. After that, I had a live code challenge with one of their engineers.

When I asked the recruiter what the problem was and the reason for rejection, although I was doing well in the interviews, she replied, "The engineer didn't feel you would fit."

Really? Are you selecting applicants according to the interviewer's feelings? And if you ask why, the recruiter will give you a block on LinkedIn. The processes weren't professional at all.
