Do you use what you studied in college?

For some careers you will use what you learned in college. For others you may not. In becoming a plasma fusion research scientist I certainly used my undergraduate physics major. When I taught at the National University of Singapore I saw that businesses were eager to hire physics majors because they knew our graduates must be smart, worked hard, and were 4 years more mature than high school graduates. The college degree filtered out the better candidates for the employers.
