I can't stand how poorly sound-isolated the conference rooms and offices are. I have literally been standing outside a conference room, waiting for my meeting to start, and overheard the details of a company shutting down. The private offices that we pay good money for aren't much better. Because they use single-paned glass (cheap) you can hear every foot step, conversation, or other random noise from any office or hallway near you.

What's even more hilarious? Our door locks seized closed for a couple of days, and their fix was to just open all of the locks and leave the entire WeWork unlocked with a single security guard there during business hours. Ridiculous.

I think there are pretty big differences between people in terms of how much sound insulation they actually want. I find that the insulation provided by the single (floor to ceiling) pane of glass in a WeWork office is more than enough for my tastes. I usually leave the door open if I'm in the office alone.

I have never overheard a conversation in an adjacent office. You can sometimes hear what people in the hallway are saying, which doesn't bother me at all.
