I’m a retail manager and I won’t say “i don’t hire people who list multitasking” because I hire anyone with a pulse but I always roll my eyes at that.

It’s not a brag. It’s admitting you either lie or you are stupid. The brain doesn’t multitask effectively. Theme the facts. The brain “task switches” and that has a delay. Thinking faster than other people is a thing. No one is multitasking and I’d never as someone to attempt it.
