Someone mentioned "At 12 months they’re likely just becoming an effective employee"...

I haven't seen a job like this in a decade or more. The last two jobs I had expected you to be fully productive in a month, and if you not had made major contributions in by 12 months (and more specifically didn't fit in with management) you were going to be let go. Letting go of employees used to be relatively rare, but I find it's becoming standard practice these days.

I can't think of a single job I've had where ICs weren't deploying code to production within two weeks and at full productivity in about a month.

Decades ago it used to be the case that you could take time to fit in, find your strengths and start growing. But the idea that you would "just be getting started" at 12 months is laughable.

Job "hopping" used to make sense a few years ago because it was the fastest way to get promoted. Now I would say it's an essential survival skills as any place you aren't happy at is likely seeing that an planning when they can start to pip you.
