Even if I managed to angle my monitor right, put on headphones, and pull my hoodie up to reduce distractions some side conversation or impromptu stand up would inevitably distract me and pull me out of my flow. I tried to come in as late as practical in order to stay late so I could get work done for a few uninterrupted hours. I found myself going in a day on the weekend to actually get the previous week's work finished. Unfortunately management doesn't like people coming in "late" because they can't lord over them from their offices during the day and constantly interrupt them with meetings.
It was downright insulting that a $5b building intended for professionals didn't have real offices with fucking doors. At the upper management level the fact the company worked as well if not better with WFH policies must be incensing. It makes plain the insipid claims about "collaboration" in that stupid building. Collaboration happens when engineers want to share ideas, not because they're imprisoned in a glorified fish tank for eight hours a day.
