Anecdotes:

I had what seemed to me a standard office, door but no window, in 2008 at my first job out of school at IBM in Austin. Some folks in that same hallway were doubled up but I was lucky to have one to myself while there.

A few jobs later in 2011 I also had one with a door, wall was a half-frosted window onto the hallway, was doubled up with another new hire eventually, this in SoCal, Ventura County.

Then in grad school from 2012 in NYC, also had a closet-scale office I shared with one of a rotating cast of officemates, that had an exterior window, nice view of 1 WTC as it was going up.

Since then (2016 on) it's been open offices, but at least with individual (if joined) desks, then WFH.
