Codingame is a good tool for assessing programming skills. By no mean we consider it sufficient to hire good software engineers, so we also perform more interactive assessments in complementary interviews. But it is perfectly suitable to get a sense of some basic algorithmic and mastery of a given language. What I appreciate most:
- Ease to create campaigns in various programming languages
- Ease to check the assessment results
- Ease to get a sense of where the candidate is compared to the industry standards
- Very good questionnaire in Java and SQL
