I applied online. The process took 3 weeks. I interviewed at YouScan (Kyiv, Kyiv) in May 2025
Interview
The interview process consists of several stages. It begins with a background and experience check to assess the candidate’s overall suitability. This is followed by a brief live coding session designed to evaluate their understanding and practical application of async/await fundamentals. Afterward, candidates receive a home task that involves designing a proof-of-concept terminal using object-oriented programming principles. The process concludes with a system design interview aimed at evaluating their architectural thinking and ability to design scalable, maintainable systems.
