I personally have never really experienced distractions as negative for my productivity. Of course it is annoying to be interrupted in the middle of something, but usually getting back to the task takes a few minutes at most. I never understood how people on the Internet tend to be so upset about it.
Experiences vary wildly. Do you have daily standup from 9am-10am, followed by a short call at 11:30, planning/sync with another team at 13:30, maybe a 1:1 at 16:00? And don’t miss our community event at 17:00! Plus minor interruptions during the rest of the day. How does that sound? This is what average days at a lot of big tech companies look like.
