No wonder there is rampant age discrimination in tech. Who wants to hire older workers who want to silo at home, avoid mentoring juniors, and force teams to have video calls when the rest of the team could have met in person?
Not the author of the OP link, but we don't find any gap between senior and junior candidates (a reasonable proxy for age) on remote preference in our data set. Every subcohort is somewhere in the high 30s to low 40s, all within a few percent and well within MOE for the size of those subgroups even if you treat the sample as completely independent (which of course it is not).
