Not really a recruiter but at interview at one place I was given a printed code example and told that there was 8 bugs and that I shield treat it like a code review.

I found 16 bugs and 4 bad practices and explained them all to the director of software engineering and team lead (that set the test), they agree that I was correct; the director turned to the team lead and said ... Are you are your a senior

I tried not to laugh lol
