Capgemini Mainframe Developer interview questions

I got a call from HR through Naukri and technical interview was scheduled. It was around 30min interview and Interview seemed very impressed. Received a call from HR next day that you are selected and asked for expected salary. In a week, I got a response saying your salary was rejected. There was no negotiation nothing only a mail saying salary was rejected. I would not suggest people going ahead with interviewing with this company.
