A real-time interview assistant works on a phone interview only if the call's audio reaches your computer. CoPilot Interview's desktop app captures the sound the computer plays, so a call on a handset held to your ear is silent to it. Two setups fix that: take the call through a softphone or web dialer on your computer, or run the Android companion app (beta) on a phone with the call on speaker. Once the audio is in, you get live captions of the recruiter's question and a structured answer in about 2 seconds, which is well matched to the short, predictable questions of a recruiter screen.
Phone screens are the first filter in most hiring processes. They are usually 20 to 30 minutes, run by a recruiter rather than the hiring manager, and built from a short list of questions that rarely changes. That predictability makes them easy to prepare for and easy for a live tool to support, as long as the audio problem is solved first.
Why phone calls are a special case for a desktop app
Video interviews are easy: Zoom, Microsoft Teams or Google Meet plays the interviewer's voice through your computer, and the real-time interview assistant sits beside the call in its own desktop window and listens to that output. Headphones are fine, because the interviewer's voice is captured inside the computer; your own microphone is mixed in alongside it so the report can score what you said, and a Mute mic toggle keeps only the interviewer if you prefer.
A plain phone call breaks that chain. The recruiter's voice comes out of your handset and never touches your computer's audio, so the clean capture path has nothing to work with. The fallback is the microphone: put the phone on speaker next to the laptop and the app will hear the recruiter through your mic, the same way the Android companion listens. It works, but caption quality drops with distance, room noise and the phone's small speaker, and your own voice and the recruiter's arrive on the same channel.
So the question for any phone screen is simply: how do I get this call to play through my computer, or, failing that, how do I give the microphone the cleanest sound I can?
Setup 1: take the call on your computer
This is the cleaner option. Many recruiters already send a meeting link even for a "phone" screen, and some give you the choice of a dial-in number or a link. If you get a link, click it and treat the call like a video interview with the camera off. If you only get a number, the options are:
- A softphone or web dialer. Any calling app that runs on your computer and plays the other side's voice through your speakers or headphones will work, since the assistant captures whatever the computer plays.
- Ask for a link. A one-line reply such as "Would a Teams or Zoom audio call work for you?" is normal and recruiters rarely mind.
- Forward your number. If your carrier or a calling app lets calls to your mobile ring on your computer, the recruiter dials the number they have and you answer on the laptop.
Test it the day before: start a session, press Ctrl+Shift+L to listen, call a friend through the same app, and check that captions appear. If the setup works for a friend's voice, it will work for the recruiter's.
Setup 2: the Android companion with the call on speaker
If you have an Android phone, the CoPilot Interview Android companion app (beta) is the fallback. It listens through the phone's microphone, so it cannot capture call audio or screens directly. The way to use it on a phone screen is to put the call on speaker, set the phone on the desk, and let the companion hear the recruiter's voice from the speaker. Captions and answers show on the phone.
Honest limits of this route: speaker audio in a kitchen or a car is worse than a direct audio stream, so expect more misheard words; and you are reading from a phone screen while you talk, which is harder than glancing at a desktop window. It works, and it costs nothing on the free plan, but if you can take the call on the computer, do that. There is no iPhone app yet, so iPhone users need Setup 1. Our guide to the free AI interview assistant for Android covers the companion in more detail.
What a recruiter screen asks, and how a structured answer helps
Recruiter screens ask about fit, logistics and motivation, not technical depth. The table below lists the questions that come up on almost every screen, what the recruiter is listening for, and how a 2-second outline on your screen helps. The anchors in the last column are examples we wrote to show structure.
| Question | What the recruiter listens for | How the live outline helps |
|---|---|---|
| Tell me about yourself | A 60-90 second summary that ends at this role | Key points first: current role, two relevant achievements, why this job |
| Why are you looking? | A forward-looking reason, no complaints | A one-line reason plus what you want next; press Shorter if the outline runs long |
| Walk me through your résumé | Dates that match, gaps explained calmly | Grounded in the résumé you pasted, so the order and names are yours |
| What are your salary expectations? | A range, or a polite deferral | A range phrased as a range, with a reason; see our salary answer guide |
| When could you start? | Notice period, honesty about other processes | A plain factual answer; you can type the question yourself if it is phrased unusually |
| Do you have questions for me? | Interest in the process and the team | Three questions about next steps, team size and timeline |
Because the questions are short, captions are usually complete before the recruiter finishes speaking, and the answer arrives while you take a breath. Use the key points as a checklist, say them in your own words, and only read detail if you blank. For the salary question in particular, read our salary expectations answer guide before the call so you have your own range ready; the tool cannot know your market rate.
Working the call: a short routine
- Start the session two minutes early. Press Ctrl+Shift+L to listen. Confirm the recruiter's first "Can you hear me?" appears as a caption.
- Let auto-answer run, or press ⚡ Answer. Auto-answer triggers after the recruiter pauses; Ctrl+Shift+A triggers it on demand. A new question is detected automatically after a 20-second pause in speech, or press Ctrl+Shift+Q.
- Read the caption first. On a weak phone line, a misheard word is more likely than on video. If the caption looks wrong, ask the recruiter to repeat rather than answering what is on screen.
- Keep answers short. Recruiter screens reward 60 to 90 seconds per answer. The Shorter button and Bullet points button exist for exactly this.
- Use the quiet moments. While the recruiter describes the role, type your own question into the app, such as "How should I phrase that I have another offer?"
After the call, the 📊 Summary report lists every question asked, a scorecard, and the questions a next round is likely to ask. For a recruiter screen, that next-round list is the useful part: it turns a 25-minute call into a prep list for the hiring manager interview. Our guide to a real-time interview assistant for recruiter screens goes deeper on that handoff.
What the tool does not do on a phone screen
It does not fix a bad line. Speech-to-text on a compressed, crackling call will miss words, and the outline is only as good as the caption. It also cannot answer logistics questions for you: your notice period, your visa status, your real salary range and whether you will relocate are facts only you have. The tool gives structure; you supply the facts. And it does nothing if the call never reaches the computer, which is why the setup test the day before matters more than anything else on this page.
Sessions on the free plan are up to 15 minutes, with 15 minutes a day in total, which covers a short screen or a daily practice run. A 30-minute screen needs a Standard plan (sessions up to 60 minutes) or a $5.99 hour pack that never expires. The AI interview assistant page lists what each plan includes, and if you want to compare AI interview assistants for phone use, test the audio path on each one with a real call before the day; a video demo tells you nothing about how a tool handles a phone line.
Practice the screen first
Recruiter screens are the easiest interview to rehearse, because the questions are known. Run the free AI mock interview with the job description and your résumé: it builds questions from them, reads each one aloud, scores your spoken answer out of 10 with what worked and a model answer, and ends with a report card. Three mock runs on "tell me about yourself" and "why are you looking" will do more for a phone screen than any live tool, because on a phone your voice is all the recruiter has. Our phone interview help page collects the common questions with example answers.
Follow the rules of the employer or assessment you're in — many people use it only to practice, which works on the free plan.

Does a real-time interview assistant work on a regular phone call?
Only if the call's audio plays through your computer. The desktop app captures what the computer plays, so a call on a handset is silent to it. Take the call on a softphone or web dialer, or use the Android companion with the call on speaker.
Can I use the Android companion app for a phone interview?
Yes, as a fallback. It listens through the phone's microphone, so put the call on speaker and let it hear the recruiter's voice. It cannot capture call audio directly, and speaker audio is less accurate than a call played through your computer.
Is there an iPhone app for phone interviews?
Not yet. iPhone users should take the screen through a calling app or meeting link on a Windows or Mac computer so the desktop app can hear the call. Asking the recruiter for a Teams or Zoom audio link is a normal request.
Does the free plan cover a phone screen?
The free plan gives 15 minutes a day in sessions of up to 15 minutes, with no signup or credit card. That covers a short screen or daily practice. A 30-minute screen needs Standard, which allows 60-minute sessions, or a $5.99 hour pack that never expires.
Will the recruiter hear the assistant?
No. The app shows answers as on-screen text only and plays no audio during a live session. The only thing it reads aloud is the AI interviewer's questions in the mock interview mode, which you run alone.
What should I prepare that the tool cannot provide?
Your salary range, notice period, visa or work authorization status, relocation preferences and your reason for leaving. These are facts about you, so write them down before the call. The assistant can help you phrase them but cannot know them.
