How we hire

Got your eye on a role?

### Submit application

If one of our roles has caught your eye, the first step is to submit your application. You’ll be asked for a CV, and sometimes a cover letter too. We love nothing more than seeing what you’re passionate about, so portfolios, videos and demos are always a great addition at this stage.

The process

If we think you’re a great fit, one of our team will get in touch for a chat. This will usually be an informal call, where we get to know each other a little better. After this, you’ll go into a first stage interview with the hiring team.

Interview and meet the team

This is where you’ll meet your potential manager, and some of your teammates. Sometimes these interviews include a task to complete ahead of time, which you’ll run through in the session. Aside from the task, it’s a good idea to look through our values and see how they align with your own. We also love questions — so don’t forget to use this as an opportunity to interview us too.

What's next?

After all interviews are completed, we’ll get back to you as quickly as possible. This is usually within a few weeks of applying, and slightly longer for busier roles. If our stars align, our recruitment team will be in touch with the good news! They’ll talk you through the next steps, like signing your contract and the onboarding process. If you’re not successful this time round, it's likely that you’d be great for another position so we would love to keep in touch!
