In-tray exercise at interview

[reallyneedmoresleep]

Hi All.
I have an interview coming up for a job I'm extremely keen to get.
It's a standard teaching post, not a leadership position.
As part of the interview process I've been advised I need to complete a 30 minute "in-tray exercise" and I'm a bit flummoxed! Google only seems to describe these in terms of corporate interviews.

Has anyone done one of these as part of the application process? Any tips gratefully received!

If you scroll down the staffroom posts, this had come up before and there was a link to a good teacher specific one. I hope you find it and I hope you get the job too!
