Caveat lector: I have no idea if these examples are actually what the committee is looking for. Hopefully they'll get looked at and improved collectively until they *are* a better match for what's expected.

I'm not in a position to say whether or not these are what the committee is looking for, but I want to thank you for providing examples that are not actual possible topics. We discussed providing examples, but didn't want to bias anyone's thinking about what technical topics they should/shouldn't cover.
While I am not on the committee, I want to second what Kevin said. These are good examples.
I edited the page to reflect that we will be using these as official examples!H
