- very few teams have headcount, or expecting to grow - the number of interview requests get has dropped off a cliff.
So BigTech is definitely hiring less IMHO.
That said, I am not sure if it's only or even primarily due to replacement by AI. I think there's generally a lot of uncertainty about the future, and the AI investment bubble popping, and hence companies are being extra cautious about costs that repeat (employees) vs costs that can be stopped whenever they want (buying more GPUs).
And in parallel, they are hoping that "agents" will reduce some of the junior hiring need, but this hasn't happened at scale in practice, yet.
I would expect junior SWE hiring to slowly rebound, but likely stabilize at a slower pace than in the pre-layoff years.
