Ummm nothing seems to deliver lately...
I don't know. A good friend of mine is about to finish his MBA here in the netherlands(RSM).
40% of students can't find places for interships, forget about anybody giving a damn about an MBA or whatever. But in the long run maybe it's a good idea. And if the schools can promise/guarantee interships/campus interviews(beleive me some of the mba schools are runnnig short of their clients given the fact that many have dissolved). It costs a lot of money to do an mba and it must help you get a job if it can't then it's a waste.
But as of now,
If you're working, keep working.
If your jobless, work your ass off to get one and then keep it.
There's too much dirty water.
