Hello
Your GPA is slightly on the lower side but your superb GMAT score will make up for it. IR score will not come into the picture unless the adcoms are down to two applicants - you and another - who have very similar profiles and scores. Even then, it would be the last criteria that could hurt your application. I think your chances for ISB are pretty good. However, for HEC paris, the average work ex is 6 years so that could hurt your case a bit. In your application, you will have to come up with very strong reasons to explain why HEC is perfect you, what you can contribute to their class despite less work ex and why this time is perfect for you to pursue MBA.
Your work experience is quite unique. What are your post MBA goals? Tell me more about the leadership experiences you have had so far and extracurricular activities during and after college.
