In my (limited) experience the answer is definitely yes. Not only do they have more exposure to the concepts we need them to understand (if not necessarily the specific tools), we have just had better luck with them as employees in general. They are more likely to do small things, like all the administrative overhead that's part of a job: responding to requests in a timely manner, having good written communication skills, showing up to meetings on time, etc. I am the first to admit this is a small sample size and a lot of the cultural fit could be that the workplace is already filled with college educated staff, but I'm curious what your experience is after the hiring process is over.
