It was a google meet interview. The interviewer's behavior was super unprofessional. Without turning on their camera they just told me to switch on mine. That's not professional courtesy. If you want to switch on another person's camera you would have to switch on yours first. The interviewer didn't introduce herself. Just started with tell me about yourself. No mutual introduction whatsoever. The interviewer gave me one program, and I did the program and produced the output. The program was good and the complexity of the output was n + n. The program ran successfully. I called HR for 2-3 days to get the feedback, but no reply. After the interview, there is no communication from the company side. Also, the interviewer was a bit rude as well.
