Applied on job portal. Got an interview invitation for F2F on weekend. First round was technical interview. Those who went before me were asked to leave for the day. Even the lady who interviewed me was not so much interested. She asked few questions related to framework and asked me to write few java codes. All went well but after the discussion, she asked me to leave for the day. I guess their position was filled before itself but they took interview for formality as they already invited some many candidates for the interview. Please dont waste candidates' time if you dont have vacancy.
