Double major ECON/MATH or a ECON Major and a Applied Math minor?

I’m econ bs major and I wonder whether double major econ/applied math is worth for finding job.
Or, I just take a minor in applied math (economics) to spare time and money?
Also, what kind of job a econ student can get? I think an Econ degree is so normal…
Do I need to take the test of Actuary, CPA or CFA?
Please provide your experience. Thank you!
