After speaking to the recruiter, there was a first technical phone screen. I was told the interviewer will call at certain time just for a quick sync-up. This quick sync up lasted around 1.5 hours. He kept on grilling me into Algo/CS/DS/coding everything. A lot of stuff felt like textbook questions, some were intelligent questions. I was not prepared for this but I still did well and was called immediately for on-site interview. On-site: There were two rounds with very senior folks. Both of them were friendly. More about my experience and trying to understand how thorough I am in what I have done. I felt both of them went well. After that dead silence. Noone responded to me. I told the recruiter I have another job offer. The recruiter's response was ridiculous. "We have other candidates lined up so we cannot move further now, sorry.". Sorry? Are you telling me you need some time or are you telling me the feedback was not positive , just tell me clearly. I messaged her again and after that recruiter never bothered responding. Very unprofessional.
