<p>I don’t see how there could be significant differences in job placement. Econ will generally give you a greater variety of career options, but based on what you said your interests are, they are about equal. CAS graduation requirements I know can seem intimidating, but usually it’s pretty painless. It’s only usually hard for people who really don’t want to take classes outside their major. </p>
<p>As for acceptance rates, it’ll be hard to compare. I know CAS generally seems harder to get into, but my impression (could be wrong) is that engineering is more self-selecting for very strong math/science-types.</p>
