KnowBe4 Technical Recruiter interview questions

I was contacted by their internal recruiter via email. She asked me if I would be interested in their technical recruiter position, I was very excited and said yes would love to move forward. From there she asked me for my availability and I gave her multiple times and a very open schedule. She didn’t respond after a couple of days to set up an interview time which was extremely unprofessional. I ended up following up with her and we were able to schedule a time. The interview was very short and the recruiter didn’t even sound like she wanted to be on the phone. She was very uninterested and even sighed in the middle of the interview. It was extremely disappointing as I was very eager for the opportunity. That told me enough about the company culture and it’s a company I would want to work for
