PhD Engineer, 32+ MBA Candidate

Hi All,
I am quite confused and would really like to get some feedback. I really wanted an MBA, but am now rethinking everything.



My Profile

Nationality:
Australian (Current); Indian (former)

Education:
PhD (Chemical Engineering) (Nationally recognized Midwestern school - US)
B.Tech (Chemical engineering) (Medium-level College –India)
Strong Academics overall, finished top of class in college (percentage system; no GPA.) Perfect GPA in Grad school. Lots of academic honors and fellowships.

Work Ex:
Engineering in a development firm in Australia. By Fall 2014, I would have spent 6 years there. First couple of years as an individual contributor, next two years as a senior engineer. For the last 3 quarters of a year, working in Process Integration, this is quite a broad role.
My work experience is why I want to do an MBA, as I have seen the pitfalls involved in not looking at technology products from a consumer point of view.

Age: 32

Extra-curriculars:
Adult Black-belt in Jujitsu.
Member of local Rotary club for the last 3 years, have served in various leadership positions in the club and delivered multiple international projects.
Volunteering at local Homeless shelter for 3.5 years.
Member of Graduate student union at University and President of Undergraduate Dorm. (1 year each)
Others…

GMAT:
750 (Q50, V40) (July 2010)

Now, I have been thinking doing an MBA over the last 3 years. I gave the GMAT in 2010, but did not apply that year. I applied the next year, and did not get anywhere. I was disappointed and decided to address what I thought were the problems with my application, particularly with my work experience. Moved roles to gain wider experience. Reapplied this year, however due to multiple issues had to push the applications to round 3. Reapplied to two schools (Columbia and Booth), got rejected from both. Got wait-listed at Kellogg. Would really like to go to Kellogg, but I am not sure that I would be accepted, given that I am a round 3 international candidate.

After my recent failures, I have been rethinking my entire application strategy. I want to move to a consumer-facing role in a tech. company, and want to add business skills to my technical skills. With my current career-path, I am probably going to end up in senior-level roles with predominantly a technology focus. So I feel that I really need an MBA to broaden my choices. I am looking for product management roles in technology companies after my MBA, and have some clear directions that I would like to pursue.

However, by Fall 2014, I will be 33, and quite old as compared to the rest of the class. So should I apply again?
Also, my previous failures over the last 2 years have made me question whether I am a candidate that the schools would be interested in? The schools that I would like to go to would be Kellogg, MIT Sloan or Haas.
Also, I have put many important decisions, (starting a family, etc.) on hold because I was really interested in completing my MBA first. However time is running out:(

So I would really appreciate any thoughts on my situation. Any suggestion/feedback/criticism would be accepted gratefully. Please help.
