I just have a couple of questions. When you say "notoriously rigorous" I wonder if it was/is really more demanding than places such as mgh, duke, hopkins, michigan, etc. In other words, can one big university program differ that much from the next (I don't mean true malignancy, just how hard the work is), as opposed to comparing mgh with a community hosp program, where I would expect the demands to be significantly greater for mgh residents?
As I noted above, what makes a program rigorous or more often malignant will vary frm person to person. It is not always true that an academic program has more demands than a community program; this is the conventional wisdom but like some many "truths" it only tells part of the story.
For some rigorous might mean long work hours (but still staying within the 80 hrs), for others it might mean lack of faculty support or teaching. Of the places you've listed above, only Duke has a long-standing malignant reputation, deserved or not.
All surgical residencies are demanding. What makes it more or less rigorous will be work hours, presence of allied staff, support and teaching, personalities, etc. As my former co-residents and I have noted, people can have very different reactions to the same program; whereas some of us were miserable, others actually returned as faculty. Thus I don't know if UW is/was more demanding than any place else, but the reputation is that it was and the experience of my friend is that it was. YMMV.
Also, if this is possible, can you provide any impressions regarding the chairman and also the PD?
No because I have never been a resident or fellow there, nor met them so it would be inappropriate for me to do so. All I can say is what I've said above - that is, according to a close friend who was a fellow there, the program was certainly not interested in supporting his needs or in treating him fairly in regards to work hours, vacations, etc. Any further discussion would likely compromise his identity which is not fair to him.
If you're interested in the program, go ahead and apply as you may find it a place to your liking.
