HR is very unprofessional. Called me using whatsapp voice, no budget for phone calls? Then she asked "yes or no" technical questions thru the phone. Imagine that. Then during interview, since its covid, everyone is doing work at home and also running the interview online. The interviewer didn't even switched on their cameras during interview session. Talking to a blank screen. It's the worst interview session ever. Even small companies are doing better than them.
