Infosys Project Manager interview questions

Interview was very easy. I have completed three rounds of interview 1. Technical 2. Manager 3. HR All interviews were done in one week. I received offer letter within a week after HR round.

I was selected after clearing all interview rounds, and then I was told that my salary expectations cannot be met. I had stated the salary expectations in the beginning before any interview round. They simply wasted my time. Highly unprofessional.
