Hiring Process

Our hiring process consists of 3 different stages:

• Founder Interview: If we like your initial application, expect to schedule an interview with the founder. This interview will focus on getting to know you a bit more and will focus on explaining the culture of the project. We want to know more about why you want to join our team, how you feel about our mission and cryptocurrency now and how it fits into your overall career plan to make sure this is the right place for you.


• Technical Review: A deep dive on your technical experiences, as well as a technical discussion.


• Technical Assessment: A technical assignment which you could finish over a weekend – we will share our current proposed solution that we are working on with you, and ask you for feedback and a proposal on how you would build it, implement it, and improve it. (Note: in a scenario where we don’t move forward together after this, we will be happy to agree an hourly or daily rate for time spent on this task – we will never ask for technical expertise for free.)
