ROXX Announces Full-Scale Launch of 'Hybrid Selection Event' at ARCH JAPAN Using 'Z-Career AI Interviewer'

ROXX Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; President & CEO: Taro Nakashima; TSE Growth: 241A; hereinafter "ROXX") announces that ARCH JAPAN Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo; President: Toru Kitagawa; hereinafter "ARCH JAPAN"), an existing user of the recruitment support service "Z-Career AI Interviewer," has fully launched a "Hybrid Selection Event" across all hiring processes, leveraging the strengths of both human and AI interviews.

Background

As a leading human resources outsourcing company specializing in the construction industry, ARCH JAPAN conducts over 10,000 mid-career interviews annually. Highly valuing the smooth UI/UX for candidates and operational optimization for recruiters, ARCH JAPAN adopted the "Z-Career AI Interviewer" in December 2025 to reduce interview workloads, alleviate interviewer burdens, and maximize hiring opportunities by improving candidate convenience. Since implementation, ARCH JAPAN has advanced recruitment DX using AI interviews and has now designed a new "Hybrid Selection Event" combining human and AI interviews to further optimize the selection process.

Previously, individual web interviews were conducted. However, limited interview time meant significant portions were spent on company introductions and candidate information gathering, making it difficult to allocate sufficient time for deep, personalized conversations or effectively communicate the company’s and job’s appeal. As a result, the interview—intended as a mutual understanding session—failed to fully deliver its value for both the company and candidates.

To address these challenges, ARCH JAPAN has integrated the AI interview’s strengths—meticulous questioning and objective, fair evaluation—with uniquely human capabilities such as emotional nuance detection and cultural fit alignment, creating a new operational model designed to maximize outcomes within limited time, now fully launched.

What is the Hybrid Selection Event?

After introducing AI interviews, the following streamlined and effective process is implemented:

Group Information Session

Multiple candidates enter an online interview room to watch a company introduction video, receive supplementary explanations from recruiters, and learn about the next steps in the hiring process.

Candidates Complete AI Interviews Individually

After the session, candidates receive a URL to complete the AI interview at their own pace. This completes the majority of candidate information gathering previously done during live interviews.

Objective Analysis by AI

After the AI interview, evaluation reports generated by AI organize and visualize response patterns, characteristics, and objective analysis results on the system. Recruiters review this data to understand each candidate’s personality and traits.

Individual Interviews for Mutual Understanding

Recruiters conduct one-on-one interviews with candidates selected for the next stage, using AI analysis as a reference. This time is dedicated to answering candidate questions, explaining company and job appeal, and aligning motivation and values to deepen mutual understanding.

End of Hybrid Selection Event

Expected Improvements

① Increased Recruiter Productivity

By consolidating individual company introductions into a "group briefing" format, physical interview time is reduced. The saved resources can now be redirected toward personalized candidate engagement and deeper mutual understanding.

② Sufficient Interview Slot Availability

Previously, interview slots could not keep up with application volume, leading to scheduling difficulties and candidate delays. Transitioning to the hybrid model allows simultaneous processing of many candidates, significantly increasing available interview slots.

③ Hybrid Design Combining the Strengths of AI and Humans

While AI interviews excel at careful listening and objective evaluation, conveying company appeal and motivation is more effective through direct human dialogue and emotional engagement. This hybrid format optimally leverages AI’s strengths (detailed questioning, objective assessment) and human strengths (personalized dialogue, attraction), delivering an ideal candidate experience.

Future Outlook

ROXX will leverage the operational insights gained from ARCH JAPAN’s hybrid selection events to further support recruitment DX for large-scale hiring companies and industries facing labor shortages, helping resolve labor market supply-demand mismatches. By thoroughly standardizing and streamlining processes with AI while strategically integrating human interaction to maximize engagement, ROXX will continue pursuing the future of next-generation HR services.
