Aaron Tiley for WSJ:
From its fiscal year-end in September 2019 to September 2022, Apple’s workforce grew by about 20% to approximately 164,000 full-time employees. Meanwhile, over roughly the same period, the employee count at Amazon doubled, Microsoft’s rose 53%, Google parent Alphabet Inc.’s increased 57% and Facebook owner Meta’s ballooned 94%.
So far, Apple hasn't annouced layoffs of any size. In fact they havent'd done any massive layoffs since 1997 - this was when Steve Jobs returned to a struggling Apple to turn things around and had to lay off 4,100 staff members.
I think Apple has never overhired and looks like their philosphy of building prducts is so ingrained that they tend to hire the right people for the job. It's a good way to remain lean and efficient.
