Salary completely depends on the place that you work. A good company will offer something betweek 40K - 150K depending on your previous experience. Basically it means to scrape/gather/analyse data from online/offline resources and make meaningful insights out from it. I don't think you will need that much of a deep stats knowledge, but preferable to have coz then you can justify whatever the insights you build using stat bases. Good programming skills will definitely help (python, R, SQL, SAS, QGIS). Can I know the company you are going to join/applied? (just to know)
