The full answer
Application review: the team reads your CV and the work you link to. Clear examples of what you built and your role in it make this stage much easier to pass.
Conversation with the team: you talk with people you would work alongside about your experience, the projects you are proud of and how you approach problems. It is also your chance to ask how Creuto runs projects and what the role involves.
Practical exercise: you complete a task relevant to the role. For an engineer it may involve code or system design, for a designer a design problem, for QA a testing scenario. It reflects the kind of work you would actually do.
Final discussion: a closing conversation covers anything left open from earlier stages, along with the details of the role. Exact formats vary by role, and the team will explain what to expect at each step.
To prepare, review the role description on the careers page, be ready to talk through two or three projects in detail, including what went wrong and what you would change, and come with your own questions about the team and the work.
