Wow. So many responses. Thank you so much, kind people. All of these are great points!
My ask out of an MBA is a lot more than just a shift or a focus to the PM role. It is the need for the immersive experience it offers. Hence the dilemma about postponing the MBA and letting the admit go.
There is another couple of pointers I realised I missed out in the initial post - Firstly, I have less than 3 years of work experience at this point. PM is a transition and may help me gain more clarity on what I want to do. On the flip side - an MBA may help me discover a path I didn't even know I could like or pursue. Secondly, this position will require me to relocate from my country to the US which involves a relocation payment of a significant amount that I will have to return in case I leave before 12 months.
If this is an international experience, it will only add to your profile.
Ask yourself a question - if you got such a great application (of course, profile, essays, etc.) now, can you make it better next time?
If yes, then, this job is just making you even better. give it a shot for 2 yrs. If that is what you want, then you will have more focused profile and reapplicants are not looked down at anyway.
If you think this admission was a fluke or a chance then you have a decision to make. The job certainly makes you a better candidate - very great company, international experience and of course money too.
Sure, there are many things you will have to think through. Just as
m B Singh said, take a time to think about it. Take your time..
And hey, congratulations!!
