With a 700 and your work in a very strong industry you are in pretty good shape for HEC.
I would definitely lean heavy on the "multi-national" management. Even better is if you have leadership abroad.
Your TOEFL is a bit weak, so I would suggest emphasizing any work you do in English and any other experience you have witht he language
As for your goals, I would focus more on Project Management than finance. Finance people, even in industry, tend to come from finance, and it doesn't make as much sense as the move from Engineering to PM.
Best of luck to ya.
