5. Our process

There are a total of 2 rounds of interviews.

The first round is “bring your project.” We want you to show us a project you have built that you are passionate about and/or proud of. Walk us through why you chose the project, how you built it, and your takeaways from it. Please bring an open-source project as we would also like to examine your codebase. This is also a chance to get to know each other better and understand the team scope.

The second round is “solve a problem.” Based on your preference and skills displayed, we will assign a suitable challenge for you to solve. You will then be asked to present your solution and walk us through your process. You are welcomed to use AI tools to help you solve the problems, but we expect you to still be able to explain yourselves.

If you are a senior SWE, there will be a third round to discuss alignment and long-term vision.
