Well now you&#x27;ve changed the goalposts with &quot;a reasonable amount of time&quot; and self-study rather than industry experience. More to the &quot;experience&quot; point, I can&#x27;t think of many jobs that will expose you to the sheer breadth of a good undergrad CS curriculum: think a <i>solid foundation</i> in algorithms, networking, calculus, linear algebra, databases, advanced algorithms (randomized, approximation), programming languages, compiler design, ai of various sorts, numerical methods, theory of computation, to name the big ones.
