Is MBA for you?
Are those post MBA jobs interest you?
Is there any other alternatives to choose?
And, if the conclusion is - yes, I want to learn something new, and I want to get trained. <-- do you think it's a good reason for a top 15 US MBA degree?
I know there are some free B-schools in scadinavia and German, don't you think it is even a better choice for you?
Think more, and
discuss with more people before making a decision
