Person sounds completely insufferable and probably narcissistic. They would be 100% a micromanager who look at long (unpaid) hours as a badge of honour.

His family situation, property achievements and ex-athlete status are completely unrelated to work but they make it part of their personality.

At the start he'd all friendly and cheery, give it a few weeks and the nightmare would start.

Also, he seems like the type who would call people 'champ' and mean it.
