Thanks for posting. A lot will depend upon your GMAT (in that, while a 700+ won't necessarily get you into top programs, below that would be an easy reason for a rejection).... so keep that in mind first and foremost!!
Even with a strong GMAT, you'll still need to work on how to stand out from the crowd, particularly with a common applicant profile of Indian (male?) with an engineering background. It's good that you have some management experience, leading teams, and some other outside-the-workplace activities. But so much at this point will depend upon your essays.... that is the place in your application where you aim to BE REMEMBERED and really show what you will bring to the class, that is different from everyone else. At present I would believe it'd be fairly challenging to get into the top 10 or so programs, particularly top 6-8. What might give you a chance is working with a consultant to really brainstorm about what you can present that makes you unique and really put together outstanding essays.
It's difficult to suggest specific schools because so much of it depends on what you are looking for in a school. I am less familiar with placements in telecom consulting specifically as well, but you can look up hiring profiles/employment stats on every school's website and see which send candidates that route for example.
(Side note-- no, shouldn't need to provide proof of top 10% per se, but theoretically a school can research/verify academic info at any point so I would think they could determine that or ask the school if really desired?)

Wishing you the best!
