The first interview went smooth with four interviewers. The fourth interviewer was not mentioned on the interview invitation email though. They didn't mention salary during first interview and I did not either. After that interview, they immediately contact me via phone for the second on site interview in two days which was a bit difficult. Traveling for more than 5 hours to give an interview in short notice period. I was going on vacations from next day for two weeks as well. So, I politely asked to reschedule they agreed on phone first and then never contacted again. I tried to reach them out via emails and phones but they didn't answer. I also asked during that phone call to give me a salary range for this position before traveling to another city for an interview. They agreed on that, too. After a week, they simply rejected me with a general email. Perhaps, I shouldn't have asked for the salary range
