I agree with the comments here.
Residents and attendings notice the things the students are doing/not doing. It's not hard to spot a douche. Any student that throws another student under the bus, especially around an attending, shows his true character by so doing. That's the type of student programs don't want, and if they do want that type of student, that's the program I don't want!!
I find it's much better when programs separate the students and have them following different attendings and residents or at different clinics/hospitals. Takes a lot of the competitiveness out and allows the students to really show who they are.
Hope the student wasn't from Western, we've been out on externships for a couple of months now.
