Thanks for the reply Hjort.
I would like to pursue MBA mainly in the US and Europe (INSEAD).
In the US, I would like to stick to the bay area (either stanford or berkeley), but that is not a strong preference. If I get into a good school I'll be glad to move there
Yes, you are right. I would like to start wiht something at a broad level and as things interest me, I would like to specialise/dig deep into it.
I am not so sure I want to move away from engineering totally. I would like to be able to use business knowledge in conjunction with a technical background. Move up the ladder to make bigger decisions..probably be armed with the set of skills a CTO has,for example.
