But your mileage may vary: companies also understand that one big cut is better for morale than lots of small ones. The current crisis is temporary but might last a long time, so a company that thinks they might have to fire engineers eventually, could plausibly pull forward that decision in an attempt to save the business.
Times are hard all around.

YC also has a "Work at a Startup" offering, if that's the kind of job you'd like.

Good luck!
In a nutshell, the bubble put a TON of great engineers out of work. Those two companies were able to acquire talent that would have been impossible to find otherwise.
"the 3,800-person Uber engineering group could be slashed by nearly 800 people in the coming weeks under the proposed job cuts."
That's certainly not most of the cuts, but it's not negligible either.
