my tuppence worth
I changed jobs just as Covid-19 started to take hold.
my role at my previous company meant that I had to be onsite a lot of the time, because the work I was doing could only be carried out in a specific location. But they were encouraging people to WFH as much as possible.
My new company, it has been WFH unless required to be in the office (which is rare). My work involves servers and network kit spread across the globe - so it doesn't matter if I am in the office or not - VPN and RDP works fine for me.
I always hated open plan offices - not just because you would always catch any bug going round. Noisy people on the phone, or random people asking questions (generally interrupting my train of thought).
Much happier with no commute (I actually changed jobs because the new one was going to be a 10 minute drive to work rather than 30+ with my previous job), and no distractions from the work. woudl be nice to go in to the office every so often - but would not want it to be the norm - maybe a couple of days a month, or whenever something requires my physical presence.
