<p>Minoring in CS can only help your employability in the software field. However, if your intention is to work in the software industry, you might be better served by majoring in CS and minoring in MechE or Physics. Coming from a mathematics background, I can attest to the fact that you can get lots of good jobs in things outside your major… but why compete against specialists (CS majors in your case) for jobs they’re more qualified to receive?</p>
