Imagine graduating in medecine and your employer respects you to be an expert at everything all at once that is related to the human body and being able to perform open heart and brain surgery and doing x-ray imaging and MRIs and being a gynecologist and an an optometrist and a pharmacist all at once.
That’s what being in IT is like. You’re expected to know how to program microcontrollers to mainframes to fucking VCRs and knowing every programming language ever created since electronic computers exist as well as networking and cloud technology and databases, etc. AND you have to be certified in all these things to prove you know them on top of your degree.
