Tech Mahindra Sr. Software Engineer interview questions

I was interview at client location .There was just one technical face to face round.They were themselves confused about where to take the interview .I got call from chandivali location saying your interview is scheduled at chandivali while interview call letter was for nerul .They do not communicate with each other.after reaching 3 member came at reception they thought that we were selected candidates and it was final round .I told them that I was not done with single round.So one of them took my interview for 45 mins after that she asked me to leave and asked about my salary.Company like tech Mahindra is not able to give a hike even not ready to accept with same salary.
