ROXX Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; Representative Director and President: Taro Nakajima; TSE Growth: 241A; hereinafter ROXX), aiming to realize an increase in overall income in Japan and resolve labor market supply-demand mismatches through technology, conducted a survey targeting 4,755 candidates who underwent selection using its self-developed and provided recruitment support service 'Z Career AI Interviewer'.

## Introduction
Against the backdrop of hiring difficulties due to the declining birthrate, aging population, and population decrease, improving 'selection speed' to maintain applicant enthusiasm and ensuring 'fair evaluation' indispensable for preventing mismatches are critical issues in the recruitment field. In this context, the introduction of 'AI interviewing' is rapidly progressing as a next-generation solution that eliminates the burden of scheduling and evaluation inconsistencies in traditional face-to-face interviews.
Our 'Z Career AI Interviewer' is not merely an efficiency tool; it has been developed with the aim of providing an environment where candidates can approach selections 'most authentically and in their best condition,' and supporting recruiters in making more accurate decisions. This time, by visualizing the voices of candidates who actually underwent selection, it became clear that in addition to convenience such as eliminating time and location constraints, the dialogue environment without evaluation pressure from AI contributes to improving candidate performance.
This report presents the actual usage trends and satisfaction levels of candidates, as well as future technical challenges.
## Satisfaction Survey Summary
1. **38.4% of usage on weekends and evenings — approximately 30% of teenagers conducted interviews at night.**
24.4% of all users conducted AI interviews during late-night hours (8 PM to 8 AM the next day), and 19.8% on weekends. Nighttime usage was particularly prominent among younger age groups, confirming that 24-hour 'asynchronous interviewing' directly prevents the loss of selection opportunities.
2. **Over 90% across all generations support operability. Intuitive UI enables fair selection opportunities.**
Over 90% of all age groups, from teenagers to those over 60, positively evaluated the operability. This confirms that an intuitive user interface (UI) that does not depend on device or IT literacy provides fair selection opportunities regardless of attributes.
3. **One in three experienced 'tension reduction'. Provides a relaxed interview experience without interpersonal stress.**
35.7% of candidates responded that their 'psychological burden was reduced' compared to face-to-face interviews. It is suggested that the positive reactions of the AI interviewer, free from interpersonal stress, and the answer summarization function contribute to drawing out the candidates' true abilities.
4. **Room for improvement in communication stability. Comfortable user experience is a challenge with diversifying usage environments.**
The main improvement requests concerned 'communication stability' and 'speech recognition accuracy,' highlighting the adaptation to diverse usage environments as a key future challenge.
