Overplayed my hand maybe. Since when negotiating for a higher pay is an arrogant conduct?

The company is not interested in cheap talents from the budget they set and the prolonged interview process. Unless of course they duped the headhunter this way to get more candidates.

Erm... you spewed nasty things to the recruiter just because the company did not want to pay you the +20% you asked for. Is that not arrogance?

You are entitled to high ball your expectations just as the company is entitled to reject them and low ball back if they find cheaper alternatives. At the end of the day, the professional way is to negotiate and see if can meet half way. If not, just politely inform the company you would like to disengage and move on.

Take it in stride and learn to manage your emotions better next time. There is nothing wrong in negotiating for better pay, but going ballistic just because things don't go your way won't do you any good in the long run.

Hope you learn something from this.
