Recruitment|Infrastructure Engineer

Selection Process

Step. 1 Document Screening

Please submit your resume, work history (CV), and portfolio. Based on the materials you provide, we will comprehensively review your background, skills, and motivation for applying.
We will typically notify you of the results of the document screening by email within one to two weeks.

Step. 2 Aptitude Test

We conduct a standardized aptitude test (commonly used in Japanese hiring, known as the SPI test).
This is used as an opportunity for us to get to know each other from a perspective distinct from technical skills and experience.

Step. 3 First Interview

This interview is conducted primarily by the manager of the department you would be assigned to.
We will ask about your past experience, your approach to work, and your reasons for wanting to join our company, using this as an opportunity to deepen mutual understanding.

Step. 4 Second Interview

This interview is conducted by a member of our team. We will assess your fit with the team members and your suitability for the actual work involved.

Step. 5 Technical Assessment

By having you work on a task that closely resembles actual on-the-job work, we assess not only your knowledge and skills but also how you approach challenges and your thought process.
This is conducted either online or in person, with the level of difficulty adjusted according to the position you are applying for.

Step. 6 Final Interview

This interview is conducted by a member of our executive management or board of directors. We will share our company's vision and future direction while confirming final mutual intent.
We aim to proceed carefully so that both parties can reach a mutual understanding and start off on a positive note.
