When evaluating work experience, do schools count the number of years you have worked at the time of application, or the time you will have worked by matriculation?
Depends on the school. Some schools have minimums, some do not. Some are more openly friendly to younger kids (Harvard) and some seem to be more adverse (Kellogg). I will say that over the last few years things have changed - and almost all schools look less and less at years of experience.
