A whole lot of outliers then. Top companies are in person? I only know a few people in FAANG but they all work remote. Maybe different for certain tasks like on site hpc work. They are in software engineering though.
YC in person doesn't mean anything to me. These bay area types often have a screw loose and do things like have people live on site maybe even in tents during sprints. Megalomaniac behavior, not a lesson to follow.
