What should I do as a fresh grad?

If you wants to make your career in HK I see ibank and b4 are your best choices.

You will be wasting your time and profile if going elsewhere.

Moreover I will suggest you to spend few years in NY's finance sector before coming to HK. In NY you can see top monies with a global perspective, while HK is more a regional hub. So when a NY profile you will just fly higher in short time frame in HK.

Hey, you should ask yourself which field you are interested and looking for instead of asking someone else for suggestion on what job you should apply for. You are already graduated & matured! After having decided which field you are preferred, you can search & try to find the most top companies in such field for application. If you want to learn more since you are still young, you can try to apply the middle size companies. At there, you can get more experience since you may require to do various jobs/fields if you are smart enough & have ability.

Good luck!
