Selection Process
All selection processes will be conducted in Japanese. |
| Re-Challenge System |
The Re-Challenge System lets applicants who do not pass the coding test retake it during a following round. We offer unlimited retakes until the end of the final round with the aim to lower the psychological barrier of the exam. Whether you've only recently started job hunting or are already determined to work at LY Corporation, we welcome anyone interested to take our coding tests.
*The Re-Challenge System also allows applicants to apply for different positions each round. (e.g., an applicant who takes the coding test for an Infra Engineering Expert during Round 1 can take the coding test for a Software Engineering Specialist in Round 2) |
