I am hardworking and very consistent with my work. My communication with coworkers is always friendly and respectful. I am able to point out mistakes and faults without hurting the person I'm talking to.
There you go, what did you learned about me?
If you base your hiring on what people wrote about their own personality, you will hire plenty of great salesmen. They will all be able to guess what the boss might like and generate nice sounding sentences to him.
They can still be poisonous jerks. And if they do, they will be perfectly able to hide the toxic culture they created from you.
