C-LEIA: An Interactive LLM-based Simulator for Requirements Interviews

Requirements elicitation (RE) is a critical skill in software engineering, that was traditionally taught through transcripts of customer interviews. However, this approach does not develop the interviewing skills of the students. We present C-LEIA (Customer-Learning Enabling Intelligent Assistant), a tool leveraging Large Language Models (LLMs) to simulate realistic customer interviews in a chat-based interface. C-LEIA provides a scalable and immersive environment for students to practice formulating questions, conducting interviews, and gathering requirements. We conducted a study with 120 students comparing traditional transcript-based exercises with C-LEIA. Results indicate that C-LEIA offers an engaging, realistic experience that enhances RE interview skills. This demonstration showcases C-LEIA’s features and highlights its potential to complement existing RE instruction.
