For example, Google had been growing somewhat quickly for decades prior to 2020, but in 2021 and 2022 it grew by over sixty-thousand people, and the crazy growth actually started in 2020, so even more than that. Sixty thousand!
Undoing that takes a very long time--they should have been much smarter about it. You need four rounds of twelve-thousand person RIFs (whether layoffs or buyouts) to get back to the earlier growth trajectory. Each round generates several stories that hit HN.
Is this MS still dropping back to pre-Covid? I would bet at least some of it is.
This is an incorrect way of looking at it. Microsoft was growing at approximately 10-15% headcount year over year prior to COVID. If they reverted to the approximate 2020 headcount that would mean an overall decline in growth in comparison to a situation where COVID did not exist.
A company growing 10% per year would be around 7x larger 20 years later. There's a limit on how big companies can get.
