I had a few of uncles and parents who described the pre-match process. "Hmmm Dr. X. we like you and we would like to offer you a position, we also have a good applicant coming next Monday and so I will give you until this Friday to decide." It was not conducive to shopping around. Now we have the opposite problem. Way too much time and effort spent to find a few good interns. I wish I had the guts to go out of the match. I would save hundreds of hours work and I think I could lock down some good people. The students are equally over burdened and a sure thing would be attractive early on.
