assuming the above are tech heavy SWE roles, then no ofc not. theres a reason why they are paymasters and lead the pay scales for tech paying well above median.

there are multiple technical rounds for FAANG level and some of them are notoriously hard. in fact, a good part of the pre-game is studying for the technical interviews in and of itself.

whether technical interviews like whiteboard questions are a good assessment is a topic for another day tho.

bottom line - tech pays well cause the barrier to entry to most places worth their salt are high.
that being said, you dont necessarily have to have a CS degree as well. as long as you are willing to grind for the aptitude and have some kinda passion + talent for it, youd generally be a good fit. speaking from personal experience.
