Applied online on their career page for the position. Got a call after a week and an interview was scheduled. The interviewer was nice and the interview went well. However, I had no response or feedback for the same. I tried to call multiple times and write emails to the HR, but no response. Interviews said the openings are on hold and you have not been rejected. It's been 2.5 months now. Why do you guys waste your and my time if you are not looking to hire a candidate?

Questions on Unix, SQL, ITIL and what have I been working on in my current projects.
