Using an AI interview assistant for a phone interview

"Phone interview" covers two technically different things, and which one you have decides how an AI assistant can help. Sort this out first; everything else follows from it.

• A VoIP call on your computer. The recruiter sends a dial-in link and you join from a browser or app: a Zoom or Google Meet audio call, or a hiring platform's built-in calling. The audio plays through your computer.
• A cellular call on your phone. The recruiter rings your actual phone number and you answer on your mobile. The audio lives on the phone and never touches your computer.

SubcueAI's desktop app works by capturing the audio your computer is playing, so the first case is squarely in reach. The second depends on which phone rings: SubcueAI's iPhone app can listen to a call playing on speaker from a different device, but iOS never lets an app hear a call on the same iPhone. The device boundary that the how-it-works answers describe for video calls applies here, just without the video.

If your phone interview is really a computer audio call, there is nothing special about it being "phone": it behaves like any other call your computer plays. SubcueAI's desktop app captures that system audio directly through the operating system (ScreenCaptureKit on macOS, WASAPI loopback on Windows), transcribes the interviewer in real time, and surfaces suggestions grounded in your resume and the job description, with no video feed required. If the call runs in a Chrome or Edge tab, the browser extension's side panel can also assist, hearing the interviewer's side only.

The practical move is to make sure the call lands on your computer. When a recruiter offers to "give you a call," it is usually fine to ask for a dial-in link instead; most teams run audio screens through Zoom, Google Meet, or their applicant-tracking platform's calling feature, all of which join from a computer. Take it there and the audio-only round is fully supported, where the interview's rules allow assistance.

If the interview rings your mobile over the cellular network, no desktop assistant can hear it directly: the call audio stays inside the phone, which does not expose it to other devices or apps. What remains is acoustic listening, where a second device hears the call played out loud.

The cleanest version uses SubcueAI's iPhone app on a different phone from the one that rings: put the call on speakerphone, keep the iPhone within arm's reach, and Listen mode transcribes both voices and drafts an answer when you tap Get answer. The desktop app's microphone channel can do the same next to a laptop. Either way, accuracy drops compared with a VoIP call on your computer, because the audio crosses a room and speakerphone adds echo. If the recruiter rings the same iPhone SubcueAI runs on, no app can help during the call; iOS keeps that audio away from every other app.

The better fix is still to avoid the situation: ask to take the call on your computer.

Two things make phone screens easier to handle than they feel. First, request a computer dial-in when you can; it is a normal ask and it puts you back in the supported case above. A marketing coordinator whose recruiter offers a quick call can reply asking for a Zoom or Google Meet link instead; the call then plays through her laptop, where the desktop app works. Second, remember that phone screens are usually the shallowest round: a recruiter confirming your background, motivation, and basic fit, not a deep technical grilling.

That shallowness means preparation carries most of the weight, and preparation needs no live capture. Run a couple of mock interview rounds focused on your introduction and your "why this role" answer, in the browser, the desktop app, or the iPhone app. Keep your resume and a few notes in front of you (entirely fine on a call nobody can see), and you will clear most phone screens without live assistance at all. For the rounds where live help does apply, the setup tutorial covers getting call audio onto your computer.
