Southern Event Management interview questions

The interview process started whenI was contacted via phone call after I submitted my application on LinkedIn, there we set up a formal Zoom interview. On the day of the interview, I got a text reminder to confirm I was attending the virtual interview. When I joined the call, I realized I was interviewing with the CEO (which was not noted) and 3 other people were interviewing at the same time (also not noted). It was obvious the CEO did not take the time to look at our resumes, as he pretty much just talked about himself the whole time, and finally asked us midway through to tell him about ourselves and was very surprised about some of our answers (which he would have known if he looked at our resumes). He was a nice guy and easy to talk to, but we didn't do much talking. The job he explained was not the same job that was posted on the job listing, I was so confused.
