If you are on a meeting invite, there is a reason you are invited. The meeting creator wants your input. So when you get to the meeting, sit at the table. That sounds easy but sometimes when there are lots of people in a room, and you are a junior person, it may seem easier to hide in the back or sit around the outside. This may be tempting but don’t do it. You can add just as much value as the other people in that room and it is important for them to see you participating and hear your opinion, so always sit at the table.
