FIS Technical Support interview questions

I applied. Recruiter sent a message saying Manager wants to interview. No initial interview with the interview was conducted. I had questions about the salary but they weren't answered. 1st interview with the hiring manager, 2nd with the head of support and the final interview with the 2 members of the team. All the interviews went very well. I had to reach out to the recruiter multiple times to try to get an update and find information about the salary. If they had let me know the salary before the interview process started, the company's time and my time wouldn't have been wasted.
