I once went through a recruiter to secure an interview for an engineering position. He insisted that I "suit up" so I did despite knowing it was out of touch with reality. I showed up to a non air conditioned building where the head of engineering was wearing ragged cutoff shorts. Last time I ever bothered with a recruiter.

Showing up egregiously overdressed for a tech interview was a rite of passage before jobs search advice was easy to find on the internet.
