Joining a Microsoft Teams interview as a guest, or in the browser instead of the desktop client, changes nothing about how an AI interview assistant hears the call: both play the interviewer's voice through your computer's audio output, and that is the stream CoPilot Interview captions. What does change is where you pick your audio devices, how notifications behave, and how screen sharing works from a browser tab. Below: the Teams guest join flow step by step, the browser-versus-desktop differences that matter, how to pick the output device so captions appear, and a short test call to run before the real one.
The Teams guest join flow, step by step
- Click the Join the meeting now link in the invite. You do not need a Teams account or a Microsoft account to join as a guest.
- Choose Continue on this browser or Open your Teams app. Either works for the assistant.
- Type your name as you want the interviewer to see it.
- On the pre-join screen, pick your camera, microphone and speaker. This is the step that matters most; see below.
- Click Join now. Guests usually wait in the lobby until the organizer admits them, so join five minutes early.
Guests can see the chat and shared screens during the meeting but lose access to the chat when it ends, so copy anything you need before leaving.
Browser or desktop client: what differs for the assistant
| Teams in the browser | Teams desktop client | |
|---|---|---|
| Audio path to the assistant | Computer audio output | Computer audio output |
| Where you pick the speaker | Pre-join screen, then the browser follows the system default | Settings > Devices, or the device menu in the call |
| Notifications | Browser notifications plus Windows notifications | Teams notifications plus Windows notifications |
| Screen sharing | Browser picker: tab, window or entire screen | Teams picker: window or screen |
| Reliability | Good in Edge and Chrome; other browsers vary | Most stable |
For the assistant the first row is the only one that matters, and it is identical. Our Microsoft Teams page and the Teams interview guide cover the desktop client in depth.
Pick the audio output so captions appear
CoPilot Interview listens to the computer's audio output, so Teams must play the interviewer through the device the operating system treats as its output. The reliable setup is: set your headset as the default output in Windows (Settings > System > Sound) or macOS, then choose that same headset, or the system default, as the speaker in Teams. If Teams plays through one device and the system default is another, you will hear the interviewer and the assistant will caption nothing.
Plug in or pair the headset before opening Teams or the assistant, and do not switch devices mid-call. Our Windows sound settings guide covers the details.
Mute notifications and tidy the screen
Guest joins in the browser add a second source of pop-ups: the browser's own notifications on top of Windows'. Turn on Do not disturb (Windows 11) or Focus assist (Windows 10) for the hour, and silence the browser's notifications in its settings. Close other tabs that play sound; a video autoplaying in another tab goes into the same audio output and will be captioned.
If the interviewer shares their screen, Teams shows it in the meeting window; our guide to when the interviewer shares their screen covers reading a shared problem.
A test call before the interview
- Ask a friend to send you a Teams meeting link, and join it as a guest in the same browser or client you will use.
- Open CoPilot Interview, press Ctrl+Shift+L to start listening, and have them read two questions aloud.
- Confirm captions show their words, not yours, and an answer appears in about 2 seconds.
- Have them share their screen and confirm you can see it beside the assistant window.
If step 3 fails, go back to the speaker setting above. Whether you use live help in the real interview depends on the employer; follow your employer's rules, and use the AI mock interview for everything else.
Where CoPilot Interview fits
CoPilot Interview is a desktop AI interview assistant that runs as a separate window beside Teams, never joins the meeting and is not a participant, so a guest join, a browser join and the desktop client all look the same to it. Audio is streamed in short segments for transcription and is not stored on our servers; a text transcript is saved only in your Documents folder. Disclosure: CoPilot Interview is our product, so weigh what we say about it accordingly.
Frequently asked questions
Does an AI interview assistant work when I join Teams as a guest?
Yes. A guest join plays the interviewer's voice through your computer's audio output exactly as a signed-in join does, and that output is what CoPilot Interview captions. The assistant never joins the meeting, so your guest status, display name or lack of a Teams account makes no difference to it.
Is Teams in the browser different from the desktop app for the assistant?
Not for the audio. Both route the interviewer through the computer's output device. The differences are practical: the browser follows the system default speaker after the pre-join screen, adds browser notifications, and offers a tab, window or entire-screen share picker. Edge and Chrome are the most reliable browsers for Teams.
Why do I hear the interviewer but see no captions?
Teams is playing through a device that is not the computer's default output. Set your headset as the default output in Windows or macOS, then choose the same headset or the system default as the speaker in Teams. Connect the headset before opening Teams and the assistant, and do not switch mid-call.
Do I need a Microsoft account to join a Teams interview?
No. The invite link lets you join as a guest from a browser or the Teams app by typing a display name. You will usually wait in a lobby until the organizer admits you. Guests can see chat and shared screens during the meeting but lose the chat afterward.
What happens to the assistant window if I share my screen in Teams?
Ghost Mode keeps the assistant window out of screen sharing and recordings. In the browser, you can also choose to share a single tab or window rather than the entire screen. Whether live help is permitted at all is the employer's decision, so follow your employer's rules.
