Have you ever been in an interview that got awkward because the candidate kept getting stuck?

It happens all the time: a programmer is given an interview problem and an hour to solve it over the phone in a plain text editor or on a whiteboard. They take a crack at it and write a totally reasonable solution.

There’s just one hangup: the candidate hasn’t found that weird bug in their solution. If they could just run their code, it’d be super obvious. But they can’t.

We fix that.

Let candidates show off their real skills

CoderPad is an interview and screening tool designed to let candidates write programs that run. It’s simple, fast, and remarkably powerful. And it looks, feels and behaves way more like your real-world, working environment than, say, a whiteboard.

Hiring gets easier when you give your candidates the best tools and the best experience (and they definitely agree). It doesn’t hurt that it makes your life easier, too. When you collaborate with candidates on writing working code, you see a more accurate picture of their abilities — and they’ll like you better for it, too.

Easy and customizable, built by engineers for engineers

It takes five seconds from starting a live interview or take-home challenge to running a “Hello, World” in Java. CoderPad makes it easy to set up your custom environment and run code in over 30 of the most popular programming languages.

Check out our features page for all of the details.

Fast to set up, simple to scale

Single sign-on, team management, compliance, security, and privacy controls. Spend less time on your set-up or customize it fully using our API. We also offer integrations with some best-in-class applicant tracking and scheduling tools.

Don’t just take our word for it

CoderPad is by far the best coding interview tool we’ve used. It beats the pants off of all the other “live editor” services out there – and then it lets you execute code, too!

My goal is to simulate real work as much as I can in an hour. CoderPad lets me do just that – the candidate gets to write code in a language they know, run it, write test cases, and debug. It’s so, so much better than just pseudocoding on a whiteboard.

5 stars

CoderPad has been a great addition to our interviewing toolkit. With it, you can watch a candidate iteratively develop their code and then actually use the compiler for debugging. This adds a whole new dimension to the process and brings it one step closer to the holy grail of natural coding in an interview.
