It has been so long since I participated in this parlor game, and I have insomnia, so I figured I would start a type related thread.
The main reason I chose my adviser (besides his research being cool) is that he seems to be an extremely lucid thinker and very precise (but also very concise) in his lectures. His knowledge base also seems to be both broader and deeper than most of the other professors I have met.
He is Russian, and I think to American ears, a lot of what he says can seem rude or mean, but nevertheless many students he has interacted with say that he is "mean". Though most of his graduate students believe he is a good guy (though some admit that he has mood swings).
He told me that he didn't like the way the post-doc I share an office with keeps his side of the office and advised me to keep my side neat. His own office is reasonably organized.
He got mad at me for getting to a class he teaches late a few times in a row (though the time he said something, I was not technically late according to my watch). Also, he himself, shows up late fairly regularly to that same class.
He has official office hours but didn't remember when they were till a student told him.
He had duplicate notes/hw-sets/etc. on the class web site till a student mentioned it to him. He claimed he was waiting for a student to mention it to him before fixing this.
Despite this, his lectures (and associated notes) are amazing (from my perspective). He is not incredibly animated, but basically everything he lectures on is insightful and he clearly enjoys the subject. Practically every sentence he writes in his lecture notes is well crafted and imparts essential knowledge, but are made so clear that it almost seems trivial.
He apparently thought he had a lot of money left for funding, but all of a sudden, ran out. All in all, he doesn't seem that good with administrative stuff.
He gives direction that can seem, at times, to be self-contradictory--not in terms that he what needs to be done, but rather in terms of what needs to done first/now.
He sets high standards and expectations, but is rather laid back on a day-to-day basis.
So, any guesses on his type? (BTW, I may not check back for like a week, so make your best determination based on what I posted. Q&A regarding his other behaviors will be slow. Feel free to debate each other. That's always fun to read)
