ESS Recruiter interview questions

Horrible experience. First, the phone interview never happened when scheduled, I was the one that had to reach out to figure out what happened. Second, after the phone interview happened the next day, I was invited to a face-to-face interview later that week. In preparation, I was asked to create a PowerPoint presentation, which I spent a good amount of time on. Face-to-face interview went great, the 2 interviewers were very nice and answered my questions. I sent a follow-up email thanking them for their time. Over a week had passed, so I decided to send a simple, “has the position been filled?” type of email. Absolutely NO RESPONSE! As an HR Professional, that is not how you conduct business. When a candidate devotes time for a phone interview, prepares a presentation, and then goes in for a face-to-face, isn’t it customary to provide either feedback or even a simple yay or nay?
