If you want to someone to do lint, why not just run lint and save on an expensive hire?

Code reviews are there to find problems with the code that are not found by trivial static verifiers and/or IDEs. This requires a level of understanding of the language and experience in reading (instead of writing) code, but has nothing to do with regurgitating keyword definitions.

Better in that case to just give a code fragment and make them spot the (algorithmic, logic, security, not spelling) errors.
