OK, here's what we think: If you're up for it, you should take the GMAT again to get your quant up. Your verbal is great, and you technically could apply with this GMAT - but we think you can do better. You didn't answer our question on how many times you've tested so we're assuming you only did it once. And if you test again then you'll be able to present an IR score as well, which can only add value to your profile (the IR is not mandatory but it helps the adcom when you have it).
Your college record is almost definitely better than a 3.2 GPA equivalent. Where did you get that figure from? If it was officially converted by WES then we'll go with it but if it's a number you came up with yourself, we're skeptical. Isn't a 69% from Delhi near the top of your class? If so you would be more like at 3.6 at least (don't quote us on that we're just throwing out a number here). Regardless, University of Delhi is a good school, and engineering is a challenging subject.
Because you apparently did well in college then we would think you could do better on the GMAT - and that can open doors for you.
Your work experience looks like it might be more challenging - not impossible but a bit tricky if you haven't had a chance for big leadership projects. We have definitely see people like that present their background in a way that shows the adcom why they need an MBA and what they would bring to the classroom -
we just had a series of posts from one recent Success Story on the EssaySnark blahg that you may find inspiring.
With a higher GMAT score then more doors could be open to you. A high score doesn't guarantee you'll get in but a low(er) score will keep you out - and you're quite a bit below the average of 720 for Indian candidates who are accepted to the best schools.
The schools you've listed are good schools so if those make sense for you, given your goals, then you should go for it. But we're still early enough in the season that you may want to consider your options. It sounds like you're a little bit younger too which is another reason that you may want to take the time to do things right - it's always easier to get in the first time through.
We can't suggest other schools since that's a very complicated question and you never even mentioned why you want an MBA; it would be professionally irresponsible to start throwing out names when we don't know enough about you or your career goals.
Hopefully the info we have offered is useful. If you have follow-ups or we can help further please let us know.
