Business Plan for Port Management Interview position, together, Business, completed, interview

MythosHF

I have an interview next week for a position of a trainee portfolio manager.

I have been asked to prepare a business plan by this Friday in preparation for the interview.

The business plan asks me to focus on "how I plan to grow the business and what value I will bring to the role of Trainee Portfolio Manager." It's target length is 2-3 pages.

Has anybody on here completed a request such as this for a job before?

If so, what advice would you have for me in terms of putting this together?

I'm mainly concerned with format primarily and what sort of headings, presentation method I should be completing for it.

Any advice gratefully received.
