Prior preparation and planning
As with any meeting, it is important to prepare in advance. In fact, in a remote meeting, it is probably even more important to prepare, because you may only get one chance to speak.
Look at the agenda and think about the points you want to make. Condense them as much as possible to avoid wasting anyone’s time.
If you have several important points to make, it is worth emailing the host ahead of time. Tell them what you want to say and why, so that they will know to call on you in the meeting.
