The startups and small companies are playing offense - they are trying to get their foot in the door and hunting.

BigCos are playing defense - they want to maintain the status quo and not kill the golden goose. They've built a castle to protect it. It's only natural that they will add friction everywhere for the fear of killing the damn bird.

Relax and coast for a bit, and jump to a small company. But like others have said, you will work more hours, and they can be insanely high cognitive load for other reasons.
