Aerospace Technologies Group interview questions

This was a few years ago, but I had a terrible and unprofessional experience with this company. I did two phone interviews and one on-site interview for an internship. I was told after the on-site that they would get back to me next week with my schedule. A week goes by and I haven’t heard anything, so I tried reaching out via phone and email several times, but I could not get ahold of anyone. I was completely ghosted by the CPO (“chief people officer”) Michelle Glenn. I even turned down another internship opportunity for this place. Shocking how this person is in a leadership position.
