The day-to-day is basically a combination of:

* Moving data around - mostly using Excel + SQL, though R is growing in popularity

* Using that data to calculate figures that are significant to the business - including premiums, IRRs, profit margins, and the value of future claims

* Presenting the results of those calculations to management and recommending a course of action

I'm not sure what "old-school original data scientists" do/did or how similar this is.
