Over a decade ago an old boss was hiring for an electronic assembly position. Not super high pay, about $15 an hour in 2010 but no college needed only basic soldering ability. Everything had work instructions, extremely detailed point to point instructions. Think "1. Turn on soldering iron (insert picture of soldering iron with power button circled) 2. Turn temperature to 650 degrees (another picture) 3. Wait till digital display shows between 640 and 660." type of instructions. He was going to give the interviewees a simple test, basically here's a board, here's some components, read and follow these instructions, come back when you are done. The trick was if you actually read the instructions there were some odd things, like only solder one leg of this resistor or install this capacitor backwards. Theses were in the same font and size but were bold. He interviewed 10 people, 8 got immediately ignored because they installed all the components normally and didn't follow the instructions. He got called into hr and told he could never do that again. Supposedly they claimed it was racist.
