Tech people only wear sweatpants

A recruiter calls to prep me for my upcoming interview:

Recruiter: …and if they ask you what your greatest weakness is think of a negative and turn it into a positive!

Me: Mmhmm

The recruiter is being very patronising – this isn’t my first rodeo by any means.

Recruiter: And what were you planning on wearing to the interview?

Me: Clothes…

Recruiter: Ahahaha yeah good but seriously, what were you thinking of wearing?
