Yeah of course you'd bring them in for an interview to talk about those projects if they show a promising portfolio.

I just can't imagine hearing someone say "Yeah this guy is a great visual designer, look as his gorgeous portfolio, and look at all this great stuff he did at smashing magazine (or whatever good place for design, I don't know..) But he's not a team player, he is sceptical about doing 'pair-designing' for 8 hours a day with other randomly chosen incompetent designers. No hire."
