FAQs

What do I need to send to apply and how will the interview process be?

We believe in the power of passion and human connection in order to build meaningful things that matter. This is why we don’t have a highly structured interview process, but rather want to hear your story, who you are, what tickles your brain, and how you approach your work.

Here’s How Our Interview Process Works

• Motivational Message: start by sending us a short, thoughtful message about why you believe you’re the right fit for this role. Add your CV and motivation letter, and any project you’ve done in the past that helps us consider your application.
• First Conversation – Technical & Personal: if we see a good match, we’ll schedule a call with someone from our technical team. If you’ve built a full-stack project you’re proud of and would like to walk us through it, we’d love to dive into that. Otherwise, we’ll propose a code challenge. During this call, we’ll also talk about your background, previous projects, and what drives you.
• If all goes well, you’ll have a final chat with our CEO to discuss team dynamics, expectations, and your potential role.
