Segra Project Manager interview questions

Received an email of questions from HR. One question in particular I went back and forth with the Recruiter was the range in pay I was looking for. i did not engage or push the issue, but the recruiter kept emailing me about my salary expectations and how far I would go in decreasing my expectations. After a week regarding my conditions of salary and benefits, I was given the opportunity for 1:1 interview with hiring manager, which was an hour long and after every question I asked was left unanswered.
