what's your last job?

My understanding on "preparing financial statement"
is to pull data, verify all numbers form diffferent dept, and reformatting to fit filing standard, sort of thing.

prepare for LT financial planning usually requires, verify data, model and assumptions, cost of debt, sales forecast etc, to generate a DCF model(in excel) that support or dis-support a project/projects within company. If not senior level, should not be too hard to do just need to be quick and error-free. VBA and Excel macro are great essentials to know.
Good luck.
