GRE and Graduate programs for Math undergrads

[Amandarh]

I recently graduated with a B.S. in mathematics and I am considering graduate school. I'm having difficulty deciding on what kind of program I want to go into. I would like to work in data science and development or in engineering. I have considering going for a computer or electrical engineering masters but I don't feel that I would be able to get into these kinds of programs since I don't have the background. I have also considered data science. My question is what kind of programs should I consider? Could I get into an engineering program with a mathematics background and no engineering background? Also would it be better to take the math subject gre or just take the general gre? Thank you
