First of all, just pointing out I believe you posted on someone else's post/thread here?
Next time would be more useful if you created your own new post. But in response to your post.... knowing just a GMAT, academics, and that you have 4 years experience at Tata is only a part of the whole picture.... b-schools (like it or not) do not make admissions decisions solely based on those facts. They aim to make a holistic assessment of your past, present and future.... they want to know what past experiences you have that you'll bring to the table (in particular, examples of leadership, teamwork, making an impact, going above and beyond); they want to know WHY you want an MBA and why their school, and they want to know about your future goals. It should all make sense and flow.... your Past + your MBA = your Future goals.
You'll show a lot of those things through your essays, and to a certain extent, your letters of recommendation, resume, interview.
Focusing solely on your GMAT score, a 730 is great, and it means that you don't have to worry about a low GMAT keeping you OUT of any programs. IF you have an excellent application in all of the other areas, and you can show something unique about you that makes you stand out from the crowd of IT applicants, you could have a shot at top global b-schools. BUT it is so competitive at top ranked schools, that even with top scores, it is not easy to get in... so we like to caveat that statement and encourage you to apply to a range of programs, and not to underestimate the importance of excellent essays!
