Graduate / (applying for Master of Accountancy program) Ethical dilemma in professional career [4]

Hi,

I'm about to apply to business school and I have problem about writing application essay.

I'm applying for Master of Accountancy program. I don't have any experience and I have to write application essay about ethical dilemma in professional career.

Where should I get started if I don't have any experience in professional career?

Please give me some ideas

Thank you so much
