Blue Yonder Staff Software Engineer interview questions

I have been through 3 technical rounds( even with director) and hr round. They have collected payslips and ctc documents and not responding after that. The HR manager dont have basic etiquette to respond back regarding offer or negotiation. This is after a HR interview round and letting know that he will get back. Save sometime and attend other.

3 rounds technical and one managerial They collected documents and payslip but never released the offer They did not pick calls later Did not have the courtesy of informing me
