I know a guy who was an engineer at a very well known US based engineering startup that made real physical products. Lots of top engineering grads from top schools apply there. His observation of young interns from top schools was that when the fresh engineering grads (or soon to be grads) ran into a problem that they couldn't solve, many didn't know how to react or didn't take it well.

They all had been able to get that far in their academic career because they had been able to solve problems, and solve them well and quickly.

When they ran into hard problems in the real world that they couldn't solve, some couldn't handle it well.
