I cleared the OA. I was invited for an on campus interview. Few weeks after the interview I heard from a HR person saying I cleared the interview and I was invited for the Tech Night and she also said there would be another round of discussion on the day after the tech night. Until the day of Tech Night I din't receive any invite and My interview was not scheduled.Hence I emailed the HR. My interview was then scheduled for the next day. However I was scheduled for an internship interview instead of a full time. They then called me up to inform I will have a phone interview on another day and they cancelled the scheduled interview. There is no response from them for over a week and no interview was scheduled. I have to follow them again. The HR said I did not get selected from the very first round. Very unprofessional of them to give me a false update all the while. Who does that ?
