Hey there,
A lot goes into understanding your GPA and its impact. As Melissa mentioned, a GMAT is an important component in assessing your academic abilities but you can't take a GPA at face value. For example, it depends on where you went to school, what you studied, and the relative ranking among your peer set. For example, a 6.6 from an IIT > a 6.6 from most other programs in India. Also, certain degrees are more difficult than others so that factors in. Lastly, if a 6.6 puts you in the top 10%, then that's still pretty decent.
So is a 6.6 a great GPA? No. But there's a wide band it could fall in. However, context isn't taken into account when you're talking about rankings and GPAs factor into almost every major ranking source out there. Adcoms will care.
So the short answer to your question is...*drumroll*...I can't tell...yet. I'd need a bit more information from you. Like what your company is all about or if you're involved in the community. There are a lot of pieces to the puzzle and knowing how all of them fit together is important in telling you how important one particular aspect may or may not be.
