I have only had two female interviewers and YES, I have loved those two schools more than the others. I don't know if it's a coincidence or not. Frankly, I do think that there are very different issues for women going into this profession than men. It is not an easy thing to be balancing a career as a physician and a family, and however feminist I am, I acknowledge that it is traditionally the woman's job to do much of the family management. I had got really good insights into the specific decisions that these women had made in their careers. It got me thinking about far more interesting things than what class size I thought was best for me.... For what it's worth, women are very good at multi-tasking as a gross generalization, and I think that makes us more than cut out for the process of creating such a balance.
It's still a bit of an old-boys network, like it or not. There are specialties with 10% and lower representations of women. Some southern doctors I have met have literally asked me why I thought I should go into medicine instead of raising a family. Okay, that's a tangent. But the fact remains that many of the powerful people (and therefore many of the interviewers) at these schools are male. I have had 12 interviews and 2 female interviewers, so unless I am having really random luck, what you noticed is not accidental.
