This will be the trend among most tech companies. Very clear the market has now negatively reacted to high operating expenses that largely stem from excessive headcount. Most companies will likely not reduce pay if they can help it to maintain competitiveness, but if you’re a bottom or middle performer or on a non-revenue generating team suddenly your job security even at “safe” companies like Google is at risk.
Reducing staff by ~10% or whatever after doubling it in the last couple years isn't exactly a strong signal of anything.
