If you want to make a transition its best to do it while in b-school not several years later.
Thanks for your insight River.
However, as I mentioned I am want to move from Quality Engineering to Marketing (as that is the best natural transition for me. I think..). In the medium to long term I want to eventually move to Management Consulting so that I get the work-ex for overall business issues.
I mean I do want to work in marketing for the initial few years after MBA. After that, I want to move into management consulting and eventually start something.
