When working with clients, inevitably you'll find yourself in Teams calls, and it's important to keep your front-facing camera on as much as possible. There's a lot of valuable information conveyed by your face and body language.
❌ Figure: Bad example - The client feels like they are talking to a blank screen. Even with a profile picture, it feels impersonal
✅ Figure: Good example - The client can see your face, and the call feels much more relaxed and personal
Of course there are exceptions, and there are times when you should definitely not turn your camera on.
Note: It's always a good idea to have one person screensharing when pair programming
