This sounds just like one of the 135 pilots I used to fly with. He'd be at the controls, I'd be working the radios, and then he'd argue with me about what ATC was telling us to do. He was always sure he knew what was going on and didn't want to listen to me. Luckily nothing too serious happened when I was at that company other than getting yelled at by ATC a couple times.

Also, same thing where checklists were memorized. Not kidding I never saw him reference a checklist for anything, and he didn't want me picking it up either.
