[Grammar] At or in preposition confusion

[Joe333]

Sentence: "working as a teacher at/in a school"

My question/doubt: What would be the right preposition in the above mentioned sentence: at or in. I think "at" but have seen so many people using "in" that's why I'm confused. So need your help/confirmation.

Thanks

You can use either one.

I (unofficially) declare at/in questions to have taken over from 'simple past/pres perfect' questions as the most FAQ.
