With your eyes closed, tell me step-by-step how to tie my shoes.
- first reach down to your feet.
- check if you have shoes
- check if your shoelaces are untied
- if they are, tie your freaking shoelaces you're an adult gosh
Note, that's pretty uncharitable. What if it's a job interacting with disability or children? However trivial the example, plenty of jobs need you to demonstrate a strong ability to break down tasks into concrete parts and deliver them as clear instructions. Not to mention, some people just don't appreciate a good snark and/or will count my unwillingness to jump through dumb hoops on command like a purebred show-monkey against me.
In any case, showing the concrete steps and practicing each part with on-the-spot corrections would get the point across much more clearly. I have to know my audience to tailor my instructions. I won't pretend that I'm amazing at this task in the best of circumstances, it's worse when you deliberately deprive me of the tools I'd usually use to do it.
And I still like the snark answers better.
