Recent advances in immersive computing technology have the potential to accelerate development of engaging intelligent agents that can guide one or multiple phases of learner instruction as well as formative or summative assessment.

We designed and implemented a conversational job interview task based on the proposed framework. In this scenario, the avatar plays the role of an interviewer and responds to user input in real time to provide an immersive user experience. Initial crowdsourcing experiments demonstrate the promise of this approach.
