As a manager of a large team, COVID definitely made the last couple of years hard. If not for productivity, then certainly for team cohesion. It's like the famous Milgram experiment; it's just easier for people to behave in unsympathetic ways when everyone else is just a face on a screen. I also noticed that (IMHO) the 'wrong' people kind of took over the attention of the org. In person, the pillars of the org were the desk locations of the strongest engineers and mangers that helped guide the team. In this new world, the pillars of the team because the people who were the most social on Slack, creating channels and commenting everywhere. Maybe I'm getting old, but it felt like a bad culture shift.
So, I answered 'company culture' but it's really a mix of a lot of things--my framework is always 'what am I going to get out doing this job for the next few years'. If answer isn't something really important, I'm out.
