Book: The Textbook for Internalizing Recruitment from Zero

'No applications come in even after posting job listings' — The cause is not the amount spent on advertising

'No applications coming in,' 'Applicants don’t match desired talent,' 'Unstable results despite ad spending.' Many companies have responded to these three recurring issues in recruitment by increasing their advertising budgets. However, today, job seekers are increasingly entering through aggregation platforms such as Indeed, Kyujin Box, Air-work, and engage. Moreover, the widespread adoption of generative AI is changing how job listings are discovered.

This book is a practical guide that, based on these environmental shifts, explains the mechanisms behind how job listings are displayed and selected, and presents frameworks for continuous self-improvement.

Key Features of the Book

1. Goes beyond theory to show exactly 'which parts to change to get better responses' The book consistently clarifies why a method is necessary, which specific part should be revised to improve response rates, and how to apply it in practice—making it actionable from the day it’s read.

2. Covers full-scale recruitment design, not just writing job descriptions Beyond crafting job postings, the book comprehensively covers job title segmentation, job variation design, applicant follow-up, legal basics, SNS utilization, and asset-building of recruitment funnels—all in one volume. Enables holistic redesign of recruitment activities.

3. Optimizes recruitment operations with generative AI in mind Addresses critical topics currently facing practitioners, such as listing rules for the AI era and ways to streamline recruitment tasks using generative AI.

Author's Comment

'In the future, success in recruitment won’t depend on luck or intuition, but on systematic processes and continuous improvements. I’m not saying advertising spending is unnecessary—but before spending, there are always things a company can do internally. I hope this book becomes the one that changes how you approach hiring starting tomorrow.' (Takehiro Hayashida, President and CEO, Japan Adcustom Co., Ltd.)
