There are some fabulous pulmonary attendings at Stanford. Golytely mentioned some of the best ones. They pull quite a bit of weight in the medicine residency program, so if you get one of them to take a liking to you, you will probably do well.
Kelley Skeff is an interesting person, and certainly has his quirks. He is an incredible and well-respected educator, though, and works very hard on behalf of the residents. When you go around the country for medicine residency interviews, it is not uncommon for the PD at any given institution to mention Dr. Skeff's name (he runs a course series where he teaches PD's and other faculty from other institutions on how to teach). You should meet with him when you do your rotation, although he might still be on sabbatical then.
As far as not being interviewed, to clarify what Golytely was referring to, you will most likely be invited to an interview (if you got along okay with the attendings). However, on the interview day, you will not actually have any individual interviews scheduled -- you will be there for the group information meetings, tours, etc. The reasoning for this is that they feel that they already know you, especially if you've already met with the PD, so you don't have to do a repeat interview.
Stanford is a great medicine residency program. You'll see what it's like when you visit. My one piece of advice for you is to try to go to as many noon conferences and morning reports as you can, and try to get to know a few of the residents.
