STEP 1:

Initial Conversation

(30 min, virtual)

We'll chat about your experience, but we'll also dive into your approach to problem-solving. We'll ask you to share examples of how you've handled ambiguity and worked in fast-paced environments. This helps us ensure we're a good mutual fit from the start.

STEP 2:

Tech Assessment

(Complete on your own)

We'll give you a real-world, messy problem - the kind we tackle every day. You'll get to show us how you structure a solution, make assumptions and communicate.

STEP 3:

Technical Interview

(With hiring manager, in person)

We'll meet to discuss your approach to the case study. This isn't about the "right" answer; it's about the approach. We’ll challenge assumptions and talk through alternatives.

STEP 4:

Culture Fit

(45-60 min, in person)

This final conversation with a Head of Department is where we'll discuss our long-term vision and how you'd fit in. We're looking for resilience, creativity, and the ability to thrive in a high-growth environment.
