I had a similar experience with an Ivy CS grad with most of his prior work being writing code for financial services companies. Smart guy, easy to work with but tremendously messy code that often failed to take advantage of the language's standard library or the framework's utilities in favor of writing everything himself and not necessarily abstracting functionality out to classes or modules to be re-used.
