What are my prospects for the different roles in Investment Banking, Consulting and Financial News Reporting

11 A*-B, A in Maths, A, B in Sciences, 2A* in Business Studies ----Basically overall 2A* 5A 4B

A Levels ---Economics (A), Extended Project (A), Biology (C), Chemistry (C), AS Maths (C)

Bsc Economics (non-target school): 3.1 GPA...I know I did terrible

Msc Banking and Risk (Semi-target school)---results awaiting--think I will perform well

Work Experiences

Finance Directorate Intern at International Institute of Agriculture (abroad experience), Bloomberg BAT student ambassador, Field Marketer, Founded a very entrepreneurial society at university, Home Fundraising, Teaching Assistant, Administrative Assistant, Bar Staff, Retail Staff

Assuming I am successful in getting appropriate work experience in Shell Oil Company, and market related/trading work experience and I also keep up with writing and video blogging on Financial Markets news

I am particularly interested in these roles in INVESTMENT BANKING: Trading, Sales, Risk Management, Corporate Banking, Strategy or as 'a investment banker' but the hours investment bankers work is so unappealing to me.

I would also be okay with a role in Private Banking, Private Equity, Consulting and Bloomberg Business News Anchor (which I would really love--I'm a girl so you can maybe imagine).

So back to my question, do I have a chance at these roles?

Thanks
