Profile evaluation for MS in Operations Research/ MIM

[Ved]

Hi. I'm planning to apply for Operations Research or MEM/MIM/or any other business related degree for my masters studies. I'll be shifting from my Mechanical Engineering discipline. I have not take up any business related courses except for Economics and Professional Ethics. I've also done Optimization during my course work. 

With a 6.8 CGPA and a 318.5 GRE score (V - 157 Q - 157 AWA - 4.5), I'm planning to use my extracurriculars as my main focus during my applications. I've participated in two business case study competitions, one of which I was a global semi-finalist among 40 teams and I've also helped organize a case study competition of my own. I'm also a keen writer/blogger, which has given me awareness on concepts such as personal branding, content management, analytics and preparing a product like a blog.

I wanted someone's take on whether this kind of profile is seen favorably for such programs?
