Go find a bunch of free, sample financial data online. (Or, if you can't find any, it's okay if you make this up.)
Then take that sample data and use it to build a P&L statement, balance sheet, and cash flow statement in Excel. (Don't cheat. Seriously. Reconstruct the financials from scratch.)
Record a Loom video talking through the financials, how you rebuilt them, and express any areas you think the business (the one whose fake financials you're playing with) shows risk and where it's performing well.
When you apply, include all of this with it. And add a note with something like, "Shameless forecast: you need me on your team."
