Here is your profile evaluation:
Strengths: Well you have a decent extra curricular background, NGO experience is a very big help and is valued a lot internationally, so that can definitely be used in your essays to boost your application.
You have rich work experience, with the CFA level and other financial certificates you are appearing for. This can show that you are passionate about Finance and your work, and are constantly moving up( changes in job profile).
The fact that you have been working abroad will really help you out, as panels love people who have an international mindset and have been travelling or working abroad. We have done some research on it, and people with an International background are favored a lot.
Weaknesses: You have limited extra curriculars, or maybe you have just not listed it out here. So more detailed info is needed.
Also strong essays would be needed to make up for the lack of such activities and also highlight other dimensions of your life, apart from your work.
Well you have a good profile, if you really want to maximize your chances for HEC i would recommend getting a score above 710,and submitting a really great application package.
Also i would suggest targeting some back up colleges, there are some really great colleges on the level of HEC such as ESSEC, ESCP, LBS etc
