I was desperate for a job, went to at least ten interviews a week.
I got an interview at a famous furnature and decor chain (think overpriced, made by poor Malaysians/indians overseas) and the manager talked to me for 5 minutes before giving me an instruction sheet for a holiday display.
She said it was a test to see if I understood the work, so I did it, took at least three hours, no breaks and I even helped customers when they asked.
Of course I never got the job or a call back, I was just some free labor.
When businesses whine about people not wanting to work I like to remember how revolting they were when people were desperate during that time.
