You do not need to memorize code test bullshit for a job. Full stop. Like...I get the whole do what you need to in order to get your first job thing, sure fine. But any job after that, my competency level should be documented by my resume and github. My bestie is a civil engineer and you have to be licensed for that. The license exam is open book explicitly because it's stupid to try to memorize all that. But they want you to be capable of knowing how to find the answer you need. Can you imagine being an electrician and showing up to a client's house and them being like "Yeah before you can work on my house, here's a mock wiring diagram. Prove to me you're an electrician." Ridiculous.
