I both rotated and interviewed there. I spent 2 weeks in the peds ORs and 1 week on Peds pain, so my experience is somewhat limited. I felt that the residents were generally competent, confident, and friendly. I felt the staff were into teaching and building confidence to practice independently. Of the dozen or so programs where I've interviewed, it is the hardest working program I've seen. Residents, during both the rotation and the interview, universally felt they would like more time to read (or to have a life), and I was told their board scores may not be as high as other programs that allowed more time to study. There are no CRNAs here (although I've been told they are considering hiring 1-2 to help out), so this is a "learning thru working" type of program. The philosophy is that anesthesiology is a physician endeavour and that having it be an all-physician department improved their reputation/respect within the hospital. One of my interviewers discussed this at length. In my brief experience, I felt there was a good relationship btwn surgery and anesthesiology.
On the didactic end of things, there are lectures 1-2/week, with grand rounds Qmonday. There are separate lectures for CA1/2s and CA3s, I believe. On the interview day, they showed us a very nice VA with simulator and airway labs, but this is not unique to Stanford.
