Leadership believing in remote makes all the difference. We'd been doing more and more remote hiring in the years before COVID, especially when remote made a specific skillset's talent pool larger. This led to some remote-friendly, bordering on remote-first culture. When COVID hit, we adapted really fast.
I had taken a short break from Cosmos DB before COVID hit, and then accepted a new management role back on the team right as COVID was hitting. I've never seen my team all in the same room; but it's been fine/normal-ish. Now that full-remote just takes manager approval, we've had folks move away from Seattle/SF. I've got reports in the UK and NYC. It's pushed our culture to be a lot more communicative, intentional, and organized, which is good for everyone, Seattle based or remote.
What's great about all this is now there isn't even a question of "is remote ok"? We don't need to be looking for a specific skillset or a certain level of seniority. It really opens up the talent pool; recent hires have given us a lot more selection. (P.S. - I'm hiring Product Managers; permanent remote. Check out my pinned tweet on the twitter profile in my bio)
