Phone screen interview assistant for recruiter calls
The recruiter screen is short and decides whether you get a real interview: why this role, walk me through your resume, salary expectations. LastRound AI gives you a clear, resume-grounded answer to each question as it is asked.
It works whether the screen happens on a video call on your computer or as a normal phone call.
Summarized question: Walk me through your background.
I'm a backend engineer with four years on payments systems, most recently at a fintech startup.
I owned our checkout API end to end, including cutting p95 latency from 800 ms to 250 ms.
I'm looking to own larger systems, which is why this role stood out to me.

How it works
Four steps, all on the keyboard
- 1
Call on your computer: use the desktop app
If the screen is on Zoom, Google Meet, Teams or any app that plays through your computer, start a Live interview session. The app hears the call audio directly.
- 2
Call on your phone: use Mobile Copilot
Open app.lastroundai.com in your phone's browser and choose Live Interview → Mobile Copilot. Nothing to install from an app store.

Let it hear the recruiter
Mobile Copilot listens through the phone's microphone, so keep the recruiter audible to it. Bluetooth headsets are not recommended.

Generate the answer
On desktop press ⌘/Ctrl + Enter; on Mobile Copilot tap Generate Response. Mute while you speak so your own voice is not transcribed.
What you get
Built for this round
Your resume, summarised on cue
"Walk me through your background" gets an answer drawn from your resume, not a generic script.
Role-specific answers
Paste the job description and "why this role" answers lean on what the role actually asks for.
No install on the phone
Mobile Copilot runs in the phone browser and shows answers as text.
Short and speakable
Set answer length and tone in Interview Setup so answers fit a 20-minute screen.
Prepare the tricky parts
Use the Salary Calculator and Offer Comparator to know your numbers before the salary question comes.
61 interview languages

Before the interview
Fill in resume and experience first
Mobile Copilot asks for Resume and Experience before Start Interview, so do it before the call.
Check your connection
Mobile Copilot needs internet for transcription and answers, but works on modest mobile data.
Know your numbers
Decide your salary range before the call. The copilot can phrase an answer, but only you know your floor.
Where to be careful
- Mobile Copilot shows answers on the phone screen, so anyone next to you can see them.
- Bluetooth headsets that capture only your voice will miss the recruiter's side of the call.
Phone Screen Interview Assistant: FAQ
Do I need to install an app on my phone?

Which should I use, the desktop app or Mobile Copilot?
If the call plays through your computer (Zoom, Meet, Teams, a browser call), use the desktop app, which hears the audio directly and stays off screen share. For a regular phone call, use Mobile Copilot.
Does Mobile Copilot work offline?
No. It needs an internet connection for transcription and answers, but works on modest mobile bandwidth.

Sessions bill 1 credit per minute, rounded up, from Start to End. Every account gets 15 free credits a month, so you can try it on a practice round before paying. Paid plans add more credits each month.
