- An intensive onboarding bootcamp where you will be challenged, tested, and learn a ton. While we don't like firing people or having them quit, we care more about guaranteeing #2 and this process is meant to weed people out who aren't a fit.
- A highly supportive atmosphere. We have a high standard for performance, but we will do everything we can to help each individual attain it. Everyone at all levels of the company is willing to pitch in and provide advice, mentorship, or even jump in to get our hands dirty coding, organizing the backlog, or talking to
clients when a team needs extra support. We're in this together.

projects with legitimate use cases. We also build best-in-class web and mobile applications and have some of the world's best data scientists.
- The ability to work on a range of projects in different fields, industries, and stacks for companies ranging from early-stage startups to enterprise.
