> get them exposed to real, messy data

This times 1,000.

The biggest surprise to me when I got out of school was how messy things were - data, systems, management, priorities...everything.

When I went back to grad school, we had arguments about the assumptions. It was a total 180 from undergrad, and much more useful. So when I came out of grad school, I was able to deal with the ambiguities - maybe even thrived because I understood them.
