I'm not in Finance or Europe, but my opinion is that:
- 7 applications seems low. But if you're focusing on Europe, maybe it does make sense.
- I don't think your age is a problem by itself.
- If you country doesn't promote research, that probably also mean that the strength of your letters of recommendation may be limited. It seems you are doing what you can, under the conditions that you have.
- Yeah, your GRE is very low. I'm in Marketing, and here it would be too low to give much hope. I think you would need something really extraordinary to compensate that. I would usually recommend to study and take the GRE again, or maybe take the GMAT instead and see what happens.
