Our Process

We keep things straightforward and human:

1. A 30-minute introductory chat with our recruiter, Sarah
2. A 1-hour Microsoft Teams interview or on-site interview with two members of the team
3. An informal conversation with two of our Founders

We believe open, organic conversations are the best way for both sides to decide if the role is the right fit.
