Depends on the company. My stints with BigCorp life were full of 6-7PM meeting times and expectations to keep up with Slack and email even during vacations and holidays.

I have friends at Amazon who have started to miss our Saturday events because they’re feverishly working to avoid being caught in the next round of layoffs.

I also have friends at some FAANG companies who seem like they’re barely working (their own admission) so it varies wildly. Can’t really generalize.
