It is perhaps a very short and simple question, but it's an oldie and a goody:
What value will pursuing the qualification add to you?
In otherwords, what do you want to do? Having spent the last decade in commerce and industry before recently returning to academia, I would advise that there's certainly no need for a recent graduate to pursue an MBA. Indeed, without solid grounding in industry, personally I would suggest that it could well act against you. Taking a few years to ground yourself in the industrial field you want to work in would serve you extremely well in both building a strong C.V., developing valuable networking contacts, and letting you find out if it's really where you want to be longer term.
If you think that doing an MBA will automatically prepare you, qualify you, and land you a senior industry role, I would strongly encourage you to reflect on how realistic that is.
Either way, and whatever you decide to do, Good Luck!
