Agreed - If you got a Computer Science degree from an engineering school, you probably had to take Linear Algebra as one of your required classes. Also, Linear Algebra is not that hard to learn.
And you’re going to remember that at a job interview 10 years later after never dealing with it after class? Uh, no.
I took through calc 3 + discrete math, but didn’t have to take the full linear algebra course for the BS in CS. I’m sure I could refresh myself on calculus, but almost no one is regularly maintaining their more advanced math knowledge in this field.
