NCSA College Recruiting Member Support interview questions

I interviewed over the phone for this position as I was out of state while applying. The interview process was standard to what I’ve experienced in the past. I was offered the position and they jumped right into talking about start date and training. I backtracked and asked about salary. They gave me a number and when I asked them about flexibility the woman I had been speaking to told me she would check on the flexibility of the salary and then get back to me, and then I never heard back - no phone call, no email. They offered me the position and when I tried to discuss salary they completely ghosted me, they never even called or emailed me back to let me know that the salary wasn’t negotiable. I was very disappointed with how they handled what is a very standard practice when it comes to hiring and it certainly left a bad taste in my mouth regarding their professionalism and whether I would even want to work for a company that treats potential employees that way.
