I believe there were 0 admits at Wharton last year for people with no work-ex. Collegesenior got dinged this year without an interview. Having attended the admit weekends I can speak about Darden and Duke. With 4 years of work experience, I definitely found myself to be amongst the older admits.
I think that most of the schools are headed in the younger direction, some of them conspicuously, some subtly. Well, at-least none of them are shifting towards older applicants. And with people graduating, preparing for MBA, and gaining leadership experiences early, the trend is definitely for the youth but it does stop somewhere. I am sure they are trying to find the right balance between getting the best class, more energetic/moldable future alums and sharper contenders for the job market. I feel that IIM’s and US schools currently stand on opposite sides of the spectrum.
Msday, while your argument is based on the assumption that only younger applicants have experienced leadership/student management roles in school, I feel that how a person has learned, developed and gone strength to strength from those experiences is what matters. I have no doubt that a candidate with student leadership experiences that you have talked about followed by 4-5 years of good work experience where he has made the most out of opportunities will contribute a lot more to an MBA program than a candidate with great student leadership experience and minimal work experience. Plus, having seen your side and the flip side that ncprasad was talking about; he would have more complete and well-formed experiences and reflections.
Just my 2c.
