Also did one in late July. It was a pleasant experience all-around. The person who forwarded your info to the CP’s Office will go in with you. Mine was with the CP and one of the flight managers from the office. It was set up like an interview panel with them sitting across from us in a conference room. CP asked my buddy to describe me initially and asked why he thought I’d be a good fit at UA. This lead to the “why United” for me and some basic questions meant to flush out whether or not you’re someone they’d be ok spending 4 days with on the road. Super nice people and a very laid back environment. I also have heard nothing since the meet and greet.
* I brought resumes and my airline apps packet, but they had everything pulled up digitally on their phones. Business casual dress for me and my UA “sponsor.”
