Dear candidate, Our interview process is quite unusual and we understand your concern. The thorough interview process is an important part of ensuring our technical team recruits individuals with a solid technical and personality fit. The 2-week challenge is a process that every member of the technical team has gone through (from the CTO to Devs to QA). Especially for developers, this is a unique opportunity to get a personal and in-depth introduction into a number of cutting edge technologies (React, React-Native, Node etc). In 90% of the cases, the "work" done by a candidate during the 2 weeks will be thrown away. Considering the amount of time, effort and costs for us (flight + accommodation is somewhere between 500 to 2000 euros depending on the candidate location), this is a fair arrangement.
