One of the worst companies, I don't think I will join this company ever. I have clear all the rounds and HR has reacted out for final salary expectations. There was a difference in what I was expecting and what they have given and this was conveyed to the concerned HR.
To my surprise, after a couple of days, they have reached out to me saying they can't offer me because we need a SENIOR person in the team.
I think if you start negotiating with the salary they will reject, simply accept what that gives otherwise get rejected with come pointless reasons.
My suggestion would be better don't waste the time interviewing for this organization.
