Companies have always preferred to hire experienced ICs. They hired juniors because they couldn't find or afford more senior people. It does seem that a lot of juniors are being impacted. But the hiring front likely reflects the fact that there are now more senior folks in the market, and likely that they can offer lower salaries since job seekers have less leverage.
Is this true this round? I have noticed a few things:
* On the hiring front, much more demand for senior, staff, principal devs, less demand on the junior / intern front.
* (Anecdotally) A LOT of junior / new people laid off. It seems in this round companies want a small but elite force, rather than opting for junior people.
