What should I learn to get an internship?

Currently going into Finance at community college and an internship has become available through school with a local Wealth Management Company. I will be cold emailing the founder my resume and some information for (hopefully) a better shot at getting the internship.

I am going to be a freshman this year, but I have taken 20 credits already (including accounting.) What skills/applicable tools can I learn to get a leg up on this? Something like LBO models for PE, general information, not sure.

Here’s the job listing:

Research/Operations Assistant
Pay: $12/hour
Hours: 16-24 hrs/week (between hours of 8:30-5pm; 3 months or longer)

The intern will participate in research activities related to ACM’s proprietary investment strategy, and assist with operations in support of our investment advisory clients. Duties will include: participating in portfolio simulation audits; assist with stock and Exchange Traded Fund (ETF) research; assist with maintenance of our proprietary stock and research database; assist with audit and maintenance of key records; and other duties to be determined. This position will provide invaluable business experience, and could potentially
lead to full time employment after graduation. The ideal candidate will be a self-starter with a strong desire to learn. This position is suited for a student with strong math skills, knowledge of Microsoft Excel, Word, and to a lesser extent, PowerPoint. Candidates can be studying finance or general business.
