Investment Performance Analyst job?

You don't know the job your applying for.

There is no such thing.

If you mean "Investment Analyst"", they'd probably want a major in investing from a top school or an MBA.

If the job is "Investment advisor" your knowledge means almost nothing. Your ability to secure capital is what they want.

Sounds to me like you should be thoroughly familiar with Balance Sheets, Income Statements and Statement of Cash Flows. You should understand terms like profit margin, return on equity, return on assets, P/E ratios, Revenues, net earnings, debt to equity ratio's. You should also understand the term capitalization, common stock, dividend, yield, bonds, compounding interest, cash flow, free cash flow. I could go on. There is a lot to investing and performance analysis. I'm sure if you are looking for an entry position, the intend to train you. Dress professionally, look the interviewer in the eye, give him direct and not evasive answers, do not lie, do not be self-effacing. You are not compelled to air all your weaknesses and laundry in the interview. Let him know you are eager to learn and eager to make a contribution to the company. If they are investment analyst, the're going to want to make a return on their investment in you.
