Here are some tips and tricks for the show:
Sit in a quiet spot with lighting on your face, not from behind you.
Make sure your computer/smartphone is directly in front of you with the camera at eye level.
Enable the “Blur” background in Zoom (Settings > Background and Effects > Blur).
Don’t touch the camera or microphone during the show.
Stay in the same spot looking directly at the camera and don’t move around during the show.
Don’t lean on your desk, swivel your chair, tap your fingers, shuffle papers, etc.
Watch the chat box during the show to see questions and reminders from the engineer.
