Update:
Thank you eveyone who gave advice.
So here's what happened after I mentioned the negotiater that nothing less than 7.2 LPA would work for me since a 30% raise and shifting to gurgaon would mean an increase in my expenses.
To which he said, best he can do is 6.2 and said he'll call me back on Monday after I mentioned it was nice talking and cantt go any further if 7.2 is not offered.
On monday, after already clearing the background check reference, and putting my expected salary range, the HR calls me to inform, I need to get a reference check mail specifically from my former manager.
At this point, I had no doubt about not joining this organization, and sent a withdrawl email.
Still looking for a job though.
