I am doing MBA (finance 2nd year), I am very confused about which profile I should choose after completion. To be very honest I am just an average student so choosing a job which will suit me is most important otherwise I will never survive in the company. Please tell me what are options after MBA (finance) for job profile and what aptitude you require for that?

What country are you in? The notion of choosing a profile after getting an MBA sounds strange to me.
I've known MBAs who worked menial jobs while sending out their resumes to countless companies. You get what you can get. With companies able to pick the cream of the crop, you may (have)(be able) to settle for a very large company where you merely rubber stamp papers but fill the requirement for an MBA. Is that OK with you? Maybe you don't even want a business degree and would shine in a totally different field.
