Yep. At my last company we'd ask people to write an integer parser, and a task that required some very basic LINQ - a join, group by, and select.

We saw everything from completely non-functional code, to doesn't handle negatives or signal failures/triply nested for-loops respectively(partial credit OFC), to picture perfect code w/ multiple tests.

Obviously weighted very far to "completely non-functional code". It boggles my mind the amount of "programmers" who literally can't.
