The interview process was very unprofessional, with a long wait and no response. Though the interviews were not very difficult (on average), the communication with the recruiter was not giving good vibes. At the end, the recruiter said all interview feedbacks were positive and they offered me a low-ball compensation, which I asked them to reconsider. After that, they switched their statement and said one of the interview feedbacks was negative, so they were not offering me now. Clearly, the rejection was because of salary negotiation. Just to mention, I didn't ask for any higher compensation than the average listed on levels.fyi. I totally wasted my time giving an interview here.
