To me this sounds more like – engineers who have been at Meta < 3 years (so were hired remote) are performing worse than those who have worked there longer. Which...doesn't sound that crazy and doesn't have to be related to remote vs in-person at all. Of course your tenured employees are better at their jobs.
This was the most obtuse portion of the entire diatribe, and further cements my rather low opinion of Meta leadership; they have all the data in the world, but have no idea how to make proper conclusions from it.
Anecdotally... GOOG/Meta haven't updated their interview process significantly and it now just screens for quantity of leetcode grinded. This is likely a poor signal for actual engineering competence.
