Occasionally we've had the CS in first person, more often we have it in third. Our latest sheet templates are a mixture, they speak both to the character and to the player.

Going on a bit of a tangent here, but a first-person CS sounds really interesting, don't think I've ever done anything of the sort. Well, I once participated in a RP that had us filling out a normal CS, but the biography/personality section had to be narrated in first-person POV, kinda like in a job interview. It never got off the ground though, so I can't decide how useful it actually is. 

Would love to try it out some time though, because it opens up some interesting venues. What if a character isn't being honest during their description of themselves? Or what if, as is usually the case in RL, they have a skewed view of their own personality?
