at the end of the day, in your resume you just write MBA (year) (school) and that's it.
if you were obviously working during that time, they may assume that you were in an executive or part time program.
if they ask, don't lie. you may need to educate them that the executive or part time program is the same as the full time program, etc. but if they don't already know this, they probably won't believe you. hopefully this will get better over time.
if you weren't working, then they probably won't know but if you're not working, why not go to a full time program? you'll pay less money, get more immersed, and overall probably have a better experience?
