> I feel envious of these folks getting such a nice severance. It would be rather nice for me to be laid off with a great cash flow of money and take a long vacation.
I can tell you've never been laid off before, because even with severance it doesn't feel like a "long vacation".
Layoffs like this are heavily correlated with a collapsing job market. Finding a new job right now is orders of magnitude more difficult than finding a job a year ago. Getting laid off also works against you, as many potential hirers assume that laid off people were among the lowest performers of their company. It's not fair, but it happens.
It's also not really a relaxing vacation when you're busy prepping for interviews, dealing with interview calls and/or flights randomly scattered across the week, and other interview-related stresses. The clock is ticking and your full time job is now to interview to get a job. It's also likely (in this market anyway) that any company you interview with would prefer that you start ASAP, so you don't even have a defined end date.
Getting laid off with severance sounds fun until it happens and you're faced with the realities, especially in the middle of a collapsing hiring market that has been flooded with 100,000+ laid off FAANG engineers competing for every great job out there.
