KUZEN Inc. (Headquarters: Shinjuku-ku, Tokyo; CEO: Shogo Ota), developer of the LINE official account extension tool 'KUZEN,' has released a case study on the results achieved by GO Job Inc. (Headquarters: Minato-ku, Tokyo; President: Shuji Hagiwara), which operates a recruitment platform specialized for drivers.
Following the previous system implementation announcement, the company executed real-time integration with the core system 'PORTERS' and optimized the user experience (UX). As a result, effective entries increased by 2.6x and the interview implementation rate doubled, achieving significant improvements in recruitment efficiency.
Background of Implementation:
Driver roles, such as taxi and truck drivers, are critical infrastructure for Japan's logistics and mobility, but face a severe labor shortage. GO Job needed to secure a large number of drivers for its new service. However, drivers who spend most of their day driving are difficult to reach via traditional methods like PC email. To match the lifestyle of drivers who use smartphones to communicate on the go, the company shifted its communication design to focus on LINE.
The deciding factor for choosing 'KUZEN' was its scalability and expertise. The ability to integrate in real-time with the 'PORTERS' JOB hierarchy, combined with 'hands-on support' from staff with deep knowledge of the HR industry who assist with KPI setting and scenario construction, led to the decision.
Operations and Results:
After implementation, the company focused on real-time integration with 'PORTERS' and thorough 'user-centric' scenario revisions. By automatically displaying 'latest valid job openings' on LINE based on the user's desired job type and area, they prevented information mismatch. Furthermore, by changing the interview scheduling process from text input to a 'button selection format,' they made it easy for drivers to operate with one hand, doubling the interview rate. This renewal reduced the cost per offer by approximately 10,000 yen, making it highly efficient compared to other channels—1/2 the cost of job boards and 1/4 the cost of web advertising.
Future Outlook:
GO Job plans to deepen the integration between KUZEN and PORTERS to achieve more advanced personalization. They aim to automate communication based on past data for existing registrants and use AI for high-precision matching to reduce the workload for career advisors while improving the applicant experience.
