Audience interview questions

First round is a telephonic interview, After 2 days face to face interview scheduled. The best part of the interview is scheduled at 4 PM so very flexible to attend. The interview takes place in 2 days and total 5 rounds including a manager round. Even though I communicated about my expectations and holding offer letter they are not ready to pay what I have held. It's really a waste of time for me. (But I learnt something new about a technical concept i'm glad to interview panel )
