Within just 8 months of implementation, they successfully hired 2 high-class engineers.

Client Testimonial

Hired 2 High-Class Professionals in 8 Months Since Implementation: Behind the Scenes of Engineer Recruitment Using Offers

Comment from Mr. Moriyama, HR Group Manager at Coresoft Inc.

※ Excerpt from the case study interview

【Challenge】

"We struggled to build a pool of high-class engineers, including PMs, PLs, and tech leads. Our company engages in contract development as a prime contractor for prime clients and SES business as a primary contractor for major SIers, making the presence of leaders who can drive projects essential. However, the number of individuals in these positions is small in the overall market, and highly skilled talent with development experience and proactivity becomes a fierce competition with other companies. Approaching the desired candidates has become more difficult than before, even with direct recruiting services we have used for a long time."

【Initiative】

"What attracted us most was the cost advantage of not incurring recruitment fees and the AI-assisted scout message creation function (※ Recruitment fees vary depending on the contract plan).

We believe Offers' greatest strength is that it attracts many excellent engineers from the mid-career to high-class levels. We could efficiently approach the candidates we target, and we felt there were fewer mismatches after sending out scouts.

We consulted with Offers' representatives on the scout messages and tested multiple patterns using accumulated data. While trying various styles from formal messages to casual ones using emojis, the tone that received the best response was somewhere in the middle."

【Results】

"We successfully hired 2 high-class engineers, which we consider an excellent outcome. Out of approximately 13 applications, we interviewed 3 individuals who met the requirements, and 2 of them accepted our offers. Because we can connect with high-quality candidates who meet our target requirements, the offer acceptance rate is relatively high, and we feel there is little gap between the candidate profile we envisioned during scouting and the person we meet in interviews.

We were greatly helped by our account manager, who provided support based on successful cases from other companies and insights into market trends that are difficult for us to grasp on our own."
