I have talked to a few residency directors, and so far none of them gives a crap about ECs...
Agree 100%.^^
You have to realize that program directors and main attendings who will be ranking the applicants are VERY busy with patients to care for, teaching their residents and visiting students, doing admin meetings and duties at their hospital, maybe APMA, ACFAS, etc duties... and often much more. Yes, they prep a bit for interviews, but they have a ton on their plate at any given time. Chances are that unless a few students were all very good in both the clerkship/visit as well as the interview, they probably don't have the time to look very far past gpa, pod school, and board pass, research, and maybe a few other basic pieces of CV info as a screening for who gets an interview/spot.
They sometimes ask about a couple things on your resume (past jobs, positions, publications, etc) to get to know you and stimulate conversation, but you are best served by
actively bringing those things up during the interview to show you are well rounded...
"What do you think will be your best qualities as beginning resident?"
..."As an officer in my journal club, I've really learned how to search for and analyze papers, as well as evaluate levels of clinical evidence. I also found out during my APMSA rep meetings that teamwork and compromise is important."
"So, do you think you will eventually be a good leader for junior residents, and why?"
..."Well, as president of club x last year, I was frequently involved in teaching first and second year student workshops."
"Will you have trouble with the hours we work at our hospital?"
..."I don't think so. As you see, I had TA and tutoring jobs during pod school, yet I was still named dean's list regularly."
"As a first year resident, you have limited free time. What will you do with that time?"
..."As you see on my CV, I like to stay active. Intramural soccer and basketball were good ways for me to socialize as well as stay in shape during pod school."
...you get the idea. Good grades, mediocre ECs = not a big deal if you clerk/interview well. Bad/avg (depending on the program) grades and good ECs = might not even get the clerkship/interview (which basically means no shot at matching that program).
