I'm a PGY-3 at Jefferson. I was amused and a little sad when I saw this question, because I know exactly to whom these reports refer at both Temple and Jefferson. (The tough Temple interviewer is based at Moss and so also trains Jefferson residents.) I know there is only one interviewer like this at Jefferson, however, I cannot comment about Temple.
The interview style--asking hypothetical on-call situation questions, SAT scores, etc--does not reflect the atmosphere either of these attendings foster with their residents.
They are the two most "dedicated to teaching" attendings that the residents have. Both have won teaching awards from residents multiple times.
As Jefferson residents, we're very lucky to be able to work with both of them. Coming out of Jefferson, you have some of the best physical exam skills in the country because of these two attendings. (I say this after attending a few physical examination workshops at the AAPM&R this year.)
I don't know if any of you have seen scutwork.com's reviews of Jefferson, but one reviewer posted two years ago that our previous program director was akin to used car salesman. (Our current program director is wonderful.)
These "tough" interviewers are the exact opposite of a used car salesman. The more you get to know them, the more you like them and respect them. I don't know about you, but I prefer this to the other option.
