I recently started working with a new team. Immediately I noticed I was getting bowled over in meetings. Interruptions were really, really bad, with people cutting you off mid-sentence. At first I found this incredibly annoying and disruptive until I realized this was just the team culture. Everybody talks over and around each other all the time and they don’t seem to take offense to it so why should I? Instead I made sure to start speaking louder and or just ignoring when people cut me off. Now we’re all good. It’s amazing how much just putting in a little effort to fit into the established norm helped me feel better
