How to fix CoderPad not working
CoderPad is a technical hiring platform. Companies use it for live coding interviews in a browser editor, and for take-home coding tests with playback of candidates' work. Find your symptom below. Most problems come from a sign-in, a browser or microphone setting, a code run that stops, or the platform itself. Never share candidates' personal details or assessment content in a support message. Check the status page before you run an interview that is already booked.
Jump to what you are seeing
Website Down
The CoderPad website does not load for you.
- Open the page in a private window and on another network.
- Check status.coderpad.io for an active incident.
- If only your network is affected, ask IT to check the firewall.
Code Execution Failed
Code does not run in the editor, or it times out.
- Check the language setting matches the code, and that the code is complete.
- Check for an infinite loop or a very long task that may time out.
- Check status.coderpad.io, then run a short test program to check.
Video Audio Issues
The video or audio in an interview does not work for one of the people in it.
- Check the camera and microphone are allowed in the browser, and are selected in the app.
- Close other apps that may use the camera or microphone.
- Check status.coderpad.io, and rejoin once, or move the interview to a backup link agreed with the candidate.
Login Failed
Sign-in is refused.
- If the message says the password is wrong, reset it and check spam.
- Check you are using the account your company set up.
- Try a private window to rule out an old session.
API Error
Calls to the CoderPad API fail or return an error.
- Check the status code. An access error usually means the key is wrong, too many calls means you should slow down, and a server error means a service-side problem.
- Confirm the key has not been revoked and is for the right account.
- Retry with a growing delay, and check status.coderpad.io if several calls fail together.
Pad Not Loading
A coding pad or interview room does not open, or it stays blank.
- Reload in a private window, and check the link is the current one.
- Try another browser, and check your connection.
- Check status.coderpad.io, and send the interview reference and the time to the hiring contact.
Still not working?
Contact your organisation's CoderPad administrator or hiring lead first. For a platform-wide problem, contact CoderPad support through the help option in the platform or on its website. Have your organisation name, the interview or assessment reference, the exact error text, and the time with your time zone. Never send candidates' names, contact details or assessment answers in a support message. Live incident updates are on status.coderpad.io.
Most interview-tool problems come from a microphone or camera permission, a code setting or a sign-in, and they usually clear once that is checked. The status page shows live incidents, so you can see whether the problem is on CoderPad's side.
