I got a call from HR regarding an opening for Big data. 1st round a written round through video call which I cleared. I received a call for the next round after 2 days. HR said 3 slots were available and asked me to choose a slot at my convenience. I got the invite as per chosen slot. It was a 30 mins interview round. I joined at the mentioned time. Waited for 10 mins no one joined. I called HR, there was no response. Messaged and dropped a mail and continued waiting for 30 mins no one joined. I dropped another mail enquiring about rescheduling the interview, no one replied. I came to know through internal sources that particular opening is closed. I should not have given the interview after reading so many negative reviews. A highly unprofessional company that doesn't care about candidates waiting for the interview. Ignore any calls from this company
