It is as simple as: The job market looks dramatically different for today’s graduates, compared to the cohort that the linkedin ranking is looking at.
For example look at the recent data from Purdue, Cornell, and UCB in the job prospects thread, starting with this post: Job Prospects for ‘24, ‘25 Grads and beyond? - #905 by momofboiler1
What will the job market look like in five years when my D26 is a new grad? I don’t know… but I think it’s unlikely to look like the job market of a few years ago that is driving linkedin’s ranking.
