Hey Snorlax,
Overall your profile looks good.
A good school, a strong GMAT, decent internships and a diverse education( engineering+ finance)
On the flip side, the low CGPA and somewhat weak extra curriculars hamper the candidature a bit, but this is something which can be compensated for in your essays.
Coming to your questions:
1) Your 10th and 12th marks dont really play a big role for your masters, so they won't compare but yes the low CGPA can be a weakening factor, you can use your essays to mention why they are low and in parallel highlight what you did in their steed
2) For the MiM, your two internships are enough, so don't worry
3) Yes the scholarship and quiz can help, it will totally depend on the way you frame them and how they fit in with the brand you present
Overall you have a very strong chance in all 3 french schools, just work hard on your essays and other application constituents and aim to submit by round 1 of the 2018 session, and you should be golden.
