Salary negotiations

You have been selected in a well known organization. The HR has sent you an offer letter and you will be on probation for one year.

You request the company to waive off probation period since you have twelve years of industry experience. The CHRO agrees and sends you a revised offer. You revert back that salary is lower than expected. Your new boss fights for you and gets you an increase.

The HR now asks you to confirm the joining date. You request for joining bonus. The HR tells you they will revert. In coming days, you get a letter informing you that they have withdrawn the offer.

What in your opinion went wrong?
