Your observations as a recent graduate match my observations. RTO (specifically, hybrid, but that depends on the position) made a huge difference in learning and career development for younger employees at my company.

I do think it's quite hilarious that all of the older employees are claiming that their younger counterparts are doing just fine now that RTO is happening but just months ago were claiming that these newer hires were lazy or incompetent when WFH was at its zenith.
