Programmers
Programmers is Korea's largest developer hiring platform and online coding-test provider. Companies run tests from its problem bank, search and scout engineers, and conduct technical interviews.
The de facto coding test standard for Korean developer hiring. Pricey for small teams, but technical screening quality is solid and objective.
Free trial available?
No — it's a paid service. Small trials may be negotiable with sales.
Non-Korean language support?
Some problems and UI are in English, but content and support are primarily Korean.
Can overseas applicants take tests?
Yes remotely, but the user base and community are Korea-centric.
Are questions unique each time?
Companies select from a shared bank, so questions may repeat. Custom problems can be discussed with sales.
