it seems you've presented a single data point, yourself, and decided that this universally applies, which seems unreasonable.

I think most people's experiences of onboarding in new companies are somewhere in between, thus the tenure length provides another data point.

Furthermore, some hiring managers look for people that stick around for various reasons, e.g. hiring in that company is difficult due to bureaucracy, so knowing that somebody was at a company for two years vs 1 month is an important data point.
