Headstrong Senior Developer interview questions

Initial technical rounds went well. The interviewers were professional in technical rounds. Cleared 3 rounds. Further went to last final round. The guy asked for my current CTC. And also the expected CTC. I told him the number. He asked me to leave. Saying that there are employees in headstrong with more than 17+ years in headstrong and are at CTC lower than yours. Crap unprofessional guy. He did not even specify what they have to offer. I already told HR my expectation before hiring process had begun. Don't know why such unprofessional guys are in business. Such guys are reason why Headstrong is not what it used to be years back when other global leaders took it down. Other interviewers were good and knowledgable. If budget does not allow then interview should not be conducted. It costs time and money to both parties.
