Those things sound super great..... but they're of course all meant to keep you working around the clock, meeting deadlines.

This is not going to be universally true at all big tech-companies. There are places with perfectly reasonable WLB on top of huge salaries and fantastic perks.

These places are usually big enough that you're going to see extremes on both ends within the same company - some departments with huge deadline pressure cultures, and some with highly relaxed work settings. It can be a bit of a gamble.
