Kenan Advantage Group interview questions

Prescreen phone call with recruiter - first weird moment was when he said they kept reposting the job because the hiring manager only hires “senior level experience” Next was a video interview in Teams with hiring manager. He didn’t know how to start the meeting. Asked a few basic questions with follow-ups. I think he spent more time telling me about the company and the job than I talked. He didn’t like I said I enjoy being challenge and like to learn new things because he said my job would be pretty much whatever so in my current company and he can’t guarantee any promotion to a new role so I might just be bored and looked for a new job. The 3rd was an in-person interview. The hiring manager never reached out and setup the interview with everyone else and they were quite mad I never showed. I talked to the recruiter who confirm he only sent teams meetings to his staff and never told me. I still agreed to interview at this point I felt like it would be nice experience I hadn’t interviewed in person in forever. Was told to arrive 10-15 min early and the interview would be 3-4 people and it was scheduled for 30 minutes. The interview panel was 2 people and it took closer to 50 minutes because one of them asked me 20 questions rapid fire. I got so overwhelmed I struggled with some of the questions. They were all over the place testing how well I knew agile vs waterfall vs SDLC vs PMO. I immediately knew I didn’t want this person to be my peer. I don’t even know if she realized how challenging she was to talk to because she never acknowledged any of my answers just went to the next one. The other interview asked me only 2 questions. Then after being treated like I was a project and not a human the CIO came in and I had to interview with him. This was the least terrible experience of the whole process. The hiring manager then just shrugs and said “okay that’s all. We will be in touch” no thanks for coming in or it was nice to meet you. The 30 minute interview was 2 hours. Then I never heard back I saw on my application in their system it shows the job was fulfilled. I wasn’t planning on taking it because the entire process was so wacky.if a business can’t even manage the hiring process I don’t have faith in they would be a good place to work.
