* Occasionally I'll get a good conversation with a teammate or manager about something technical, but the frequency has not gone up. The technical conversations are still scheduled on a calendar and happen at the same frequency. I really haven't experienced many people stopping at my desk and I think I've only stopped at the junior engineers desk to check in.
* Socializing at work has not been my strong suit. I am pretty introverted when it comes to strangers (e.g. anyone who has not been introduced to me). I find the socializing to be more energy draining.
* I walk to work. I like that typically. The walk can be... disturbing to say the least since I walk through downtown Seattle.
* A lot of people in the office prefer to speak to each other in languages other than english. Everyone on my team (my manager + all my coworkers on my team) prefer speaking something other than english and do so unless I'm involved in the conversation. This surprised me and at times I find it frustrating because I wish I could know what they're chatting about when it's technical (certain keywords I can pickup on since they're the name of internal things).
* working in office 4 days a week has given me something to really look forward to each week, and that's the WFH day.
* I don't think my productivity has gone up. Some days it's definitely worse. Now there's an obligation to go sit and eat with others for 30min-1hr a day. Previously, I'd just bring my lunch to my desk and continue to work.
I don't think my experience is the norm. But I certainly miss the pure WFH days.
