re: Big 4 Consulting

I spent 4 years doing design engineering work before switching to ops and sales. Did that for 3 years, got my MBA and now I'm a management consultant specializing in O&G, so it can be done. You are still young enough to possibily get into consulting right now, granted it won't be at the most presitgious firm. I'd try applying to any entry level consulting gig you can find.

You may just have to go the route i did and parlay technical experience into a business role in the same industry though.
