Centene interview questions

I had a phone screening with a human resources employee. She couldn't answer even the most basic questions about the company, like how many locations do you have and which is the closest to me? They then sent me an invitation for a second interview with the hiring manager and I figured I would still give the company a shot because maybe the hiring manager would have more information. Then they ended up canceling the interview with no explanation and said they were not continuing the interview process with me. Very unprofessional, but I feel like I probably dodged a bullet.

I interviewed with this company once for a Process analyst internship. I was scheduled to interview again for the Business Process Analyst Internship. However, no one ever showed up for that interview. So, I waited on the call 70 minutes, emailed 3 people at the company, and eventually got one follow-up from a confused HR person asking if the interviewer ever showed up, and the rejection. They were timely about the rejections. However, if the potential boss in question doesn't bother to show up for the interview or respond to emails, that's kind of concerning.
