I'm a 3rd yr. commerce student, do not know what job will fit me after I graduate...
Another problem, right now I have no idea how to make a research formally.

How do I answer this? Part of me wants to scold you for taking courses and having no clue about what they will do for you in the real world. I guess you need yo talk to your guidance councelor and ask them about job opportunities in the field you are being educated in!

I graduated in Commerce (major:Marketing), my first jobs were in sales, then my interest swayed over to information technology. Now my current blends those interests. You will likely go through a few jobs before you find the type of career that grabs you.

Thank you very much:)
