Had your friend delegated the engineering hiring decisions/process to someone else, and was trying not to step on their toes?
Or friend had instituted the process, and didn't think it would go well with the other people, if you looked like a nepotism hire who bypassed the process?
Or friend was trying to put you in your employee place (where you had to meet his process), or otherwise was getting a bit full of himself, or a bit sleep-deprived and nutty?
