Hiring Process

  1. 1

    Initial Screening

    Your application will be reviewed by our engineers. Rather than just your work history, we’re looking for something that demonstrates a passion for programming. This could be a personal project or open source contributions for instance. We want to work with people who love their trade, and work to improve their skills.

  2. 2

    Two interviews

    We’ll ask you to present to us something that you’ve built and can speak passionately about. Our engineers will then ask you open ended questions about what you’ve built. We’ve found this approach allows you to highlight your strengths to us, and demonstrate how you’d fit into the team.

  3. 3


    After you pass two rounds of interviews, we’ll typically make an offer.
