Details
The Kakaopay development team developed AIVA, an AI assistant to boost productivity in the hiring process, at the 2025 Kakaopay X AWS Hackathon. The tool aims to reduce the burden on recruiters while precisely grasping applicants' capabilities.
The resume analysis feature compares job postings against resumes to analyze fit and strengths. In particular, it leverages Bedrock agent and Lambda to scrape and summarize external company information, shortening evaluators' research time.
The technical assignment analysis has an LLM review code from multiple angles, including implementation completeness, documentation quality, and test code coverage. To solve the output token limit issue, a sophisticated prompt design approach was applied, requesting each evaluation criterion in a loop format.
During development, the team resolved practical technical challenges such as prompt design, caching, and output control, gaining insights into how to use AI technology as a tool. Ultimately, they emphasized that even as AI performs an assistive role, important judgment calls must still be made by humans.
