Yes, you can use CoPilot Interview as an AI interview assistant for Webex. It runs as its own desktop window on Windows or macOS and listens to your computer's audio output. When the interviewer's voice plays through your headphones from the Webex app or a browser tab, the app captions the question and shows a structured answer in about 2 seconds. Webex is not on the list of call apps the site names, and there is no official integration or partnership with Cisco. It works for the same reason it works with any call app that plays sound through your computer.
Because Webex isn't on that named list, treat a short test as part of your setup, not an optional extra. A 2-minute test call with a friend shows whether your Webex audio settings, your headset and the app agree with each other. Below: how Webex audio reaches the app, which ways of joining work, the settings to check, the test and a fix list.
CoPilot Interview is made by NeuraSense AI LLC. It is not affiliated with Cisco, Microsoft Copilot or GitHub Copilot.
How an AI interview assistant for Webex hears the call
Your computer handles two separate audio streams during a call. Your microphone carries your voice to the interviewer. The output stream, the sound your computer plays to your headphones or speakers, carries the interviewer's voice to you. A real-time interview assistant needs that second stream, because the question arrives in the interviewer's voice, not yours.
CoPilot Interview reads the output stream on your own machine. It doesn't sign in to Webex, join the meeting as a participant or install anything into the Webex app. From Webex's side, nothing about the meeting changes. That's also why the site can say it works alongside any video app: if a call app plays the interviewer's voice through your computer, the audio path is the same. Our explainer on how AI interview assistants capture system audio covers the Windows and macOS details.
The flip side is that the app can only hear what your computer plays. If the interviewer's voice comes out of a phone, a desk phone or a meeting-room device instead, there is nothing for it to capture. That makes the way you join Webex audio the most important choice on this page.
Which ways of joining Webex audio work
A Webex invite usually gives you more than one way in: a meeting link that opens the Webex app or a browser, and often dial-in numbers for joining by phone. For a real-time assistant, they aren't equal.
| How you join | Where the interviewer's voice plays | Can the assistant hear it? | What to do |
|---|---|---|---|
| Webex desktop app, using computer audio | Your computer's headphones or speakers | Yes | The setup to aim for. Pick your headset as the Webex speaker. |
| Webex in a browser tab, using computer audio | Your computer, through the browser | Yes | Works the same way. Close other tabs that play sound. |
| Joining by phone (dialing in, or having the meeting call your phone) | Your phone | No | Use computer audio instead. Keep the dial-in number as a backup in case your connection fails. |
| Bluetooth headset paired with your computer | Your computer, through the headset | Yes, with some risk | Test the exact headset. Hands-free mode can lower audio quality and caption accuracy. |
| Webex on a phone or tablet only | That device | No | Join from your computer. The phone companion (beta) can't capture system audio. |
| A meeting-room or video device | That device's speakers | No | Join from your own computer for the interview. |
The rule underneath the table: the interviewer's voice must come out of the computer running CoPilot Interview. If you switch to phone audio halfway through, for example after a Wi-Fi drop, captions stop. Keep answering without them.
Set your Webex speaker and microphone first
Most "it can't hear anything" problems are a device mismatch: Webex plays the interviewer through one device while you expect another. Cisco's help article on selecting audio settings in Webex Meetings gives the path in the desktop app: open the menu bar, go to Meeting, then Meeting settings, then Audio. From there:
- Speaker. Choose the headset you'll wear from the Speaker drop-down and run the speaker test. You should hear the test sound in that headset and nowhere else.
- Microphone. Choose the same headset's microphone, or a separate microphone you trust, and run the microphone test.
- Match your computer's default output. Set the same headset as the default output in your Windows or macOS sound settings. When Webex and your computer agree, there's one less thing to go wrong.
- Connect before you launch. Plug in or pair the headset before you open Webex and CoPilot Interview. Switching devices mid-call can move the sound to a device the app wasn't reading.
Webex updates its menus from time to time, so if the names on your screen differ, follow Cisco's current article rather than this summary. For the operating-system side, including the permission prompts on first launch, see our guides to setting up on Windows and setting up on a Mac.
The 2-minute Webex test call
Run this a day or two before the interview, on the same computer, headset and network you'll use. You need one other person in a Webex meeting with you. If neither of you can host one, run the same test on any call app you have, then join the real Webex link 10 minutes early to check your sound. The audio path is the same.
- 0:00 — Join with computer audio. Open CoPilot Interview first, then join the Webex meeting and choose computer audio, not phone.
- 0:15 — Start Candidate Mode. Switch to Candidate Mode so the app is listening to the call.
- 0:30 — Ask real questions. Your friend reads one behavioral and one technical question at a normal pace, such as "Tell me about a project you'd do differently" and "What's the difference between a process and a thread?"
- 0:45 — Check the caption. The live caption should show your friend's words, not yours. If it shows only your voice, the app is hearing your microphone rather than the call output.
- 1:00 — Check the answer. A structured answer should follow in about 2 seconds. Glance at it the way you would in a real round, then look back at the camera.
- 1:30 — Add a messy moment. Have your friend talk over you briefly, then rephrase the question. Watch how the caption handles the overlap.
- 2:00 — Write down what failed. Fix one thing at a time and run the test again.
On the free plan, the test uses a couple of your 15 free minutes for the day, so you can rerun it after each fix. To test answer quality as well as audio, our guide to real-time interview assistant accuracy has a longer script with an answer key.
When captions stay empty on Webex
Work down this list in order.
- No captions at all. Check the operating-system permissions the app asked for on first launch, then quit and reopen the app. On a Mac, a permission change often takes effect only after a restart of the app.
- Captions show only your own voice. Webex is playing the call on a different device from your computer's default output. Set the same headset in both places and restart the app.
- Captions stopped partway through. A device changed: a Bluetooth headset reconnected, a dock was plugged in, or a monitor with speakers took over. Reconnect the headset you tested and restart the app.
- Captions arrive, but key words are wrong. Usually Bluetooth hands-free mode, a very low Webex speaker volume or a weak microphone on the interviewer's side. Switch to a wired headset, raise the volume, and ask the interviewer to repeat anything that matters.
- Nothing after you moved to phone audio. Expected. The interviewer's voice now plays on your phone. Rejoin with computer audio when your connection is stable.
- Answers feel slow. Suspect the network before the AI. Use Ethernet or sit closer to the router, and close apps that are syncing large files.

Preparing for the kinds of rounds held on Webex
Some employers run hiring on Webex because they already use it for internal meetings. The format of the round matters more than the app, so prepare for the round itself.
Recruiter and hiring-manager screens
These cover your background, your reasons for applying and logistics. The questions are predictable, so they're the easiest to practice out loud. If the screen might happen by phone instead, read our phone interview help page, because a phone call changes the audio setup above.
Panel interviews
Several interviewers on one call means more overlapping speech, and captions can merge two voices into one line. Read the caption before the answer every time. If it doesn't match what you heard, ask which question they'd like you to take first.
Technical rounds with a shared editor
Many coding rounds use a browser editor such as CoderPad or HackerRank while Webex carries the voice. CoPilot Interview's coding mode gives complete code in your chosen language, the complexity and an example run, and it can read a pasted screenshot of a problem. See the coding interview copilot page, and our live coding interview tips for narrating your approach on any call.
Practice first, whatever the format
The best preparation for any Webex round is answering out loud before the day. Mock Interview builds questions from your résumé and the job description, reads each one aloud and scores your spoken answer out of 10 with what to fix and a model answer, then gives you a report card. The real-time interview assistant page explains the live side. Follow the rules of the employer or assessment you're in — many people use it only to practice, which works on the free plan.
What the free plan covers for a Webex interview

Does CoPilot Interview work with Webex?
Yes. It listens to your computer's audio output, so it works with Webex whenever the interviewer's voice plays through your computer, in the Webex app or a browser. Webex isn't on the site's named list and there's no official integration, so run a 2-minute test call first.
Do I need a Webex plugin or add-in?
No. CoPilot Interview is a separate desktop app for Windows and macOS. It doesn't sign in to Webex, join the meeting or install anything into the Webex app.
Why does the assistant hear nothing when I join Webex by phone?
When you dial in or have the meeting call your phone, the interviewer's voice plays on the phone, not your computer, so there is nothing for the app to capture. Join with computer audio instead and keep the dial-in number as a backup.
Does it work if I join Webex in a browser?
Yes, as long as the browser plays the call through your computer's speakers or headset. Close other tabs that make sound, and test the exact browser you plan to use.
Is CoPilot Interview made by Cisco or Microsoft?
No. CoPilot Interview is made by NeuraSense AI LLC. It isn't affiliated with Cisco, Microsoft Copilot or GitHub Copilot.
Can I use the free plan for a Webex interview?
The free plan gives you 15 minutes every day in sessions up to 15 minutes, which is enough to test your setup and practice with Mock Interview. A longer live round needs a paid plan, such as Standard with 60 minutes per session, or a one-time pay-as-you-go hour.
Does CoPilot Interview record my Webex meeting?
No. Audio is streamed in short encrypted segments through our proxy to a speech-to-text model, the question text goes to the AI model you chose, and nothing is kept on our servers beyond the request. Session files stay in your own Documents folder.
