Download Interview Signal
Windows 10 and 11, and macOS 13 or newer on both Apple silicon and Intel. It installs without an administrator and needs no meeting-platform permissions.
You will need an active seat to sign in. If your agency has not bought seats yet, start at pricing; if it has, ask your admin to invite the address you use for work.
Windows
Windows 10 or 11, 64-bit. Not code-signed yet, so Windows will warn — check the SHA-256 below.

Installing on Windows
- Run the installer. It installs for your user, so no administrator password is needed.
- Open Interview Signal and sign in with your work email. You will get a link and a six-digit code; either works.
- The first time you start an interview, Windows asks for microphone access. Allow it.
This build is not code-signed yet, so SmartScreen will say “Windows protected your PC”. Compare the file’s checksum with the one published above, then choose More info and Run anyway. A signed installer is coming. If it will not install, write to [email protected] with your Windows version.
Installing on macOS
- Open the DMG and drag Interview Signal to Applications.
- Open it and sign in with your work email.
- macOS asks for Microphone access. Allow it.
- macOS also asks for Screen Recording. This is the permission that lets the app hear the candidate through your meeting app — macOS puts system-audio capture behind it. Nothing from your screen is recorded or saved. Quit and reopen the app after allowing it, because macOS only applies this grant at launch.
To check or change either permission later: System Settings, then Privacy & Security, then Microphone or Screen & System Audio Recording. The app has a link straight to both panes in its Settings screen. If it will not install or open, write to [email protected] with your macOS version.
Verifying what you downloaded
The checksum above is published with each release. To check it yourself:
Windows, in PowerShell:
Get-FileHash .\Interview-Signal-Setup.exe -Algorithm SHA256
macOS, in Terminal:
shasum -a 256 ~/Downloads/Interview-Signal.dmg
If something does not work
- No transcript at all: the microphone is the usual cause. Open Settings and check the device, then use the audio test on the pre-interview screen — it shows a live level meter for both your voice and the candidate's.
- Your side only, never the candidate's: system audio is not being captured. On macOS that is Screen Recording plus a relaunch; on Windows it is usually a virtual machine or remote desktop with no audio device passed through.
- Anything else: Settings, then Copy diagnostics, and email it to [email protected]. The diagnostics contain the app log and your machine's details, and no interview content.
