This is a good concept, but I feel like you could do more with the idea. Only having six questions for each candidate made me feel like the characters were barely explored. This works with the hiring AI reducing the candidates to numbers, but I think you could have used interactions with the other candidates to add more depth. In the game's current form, they didn't seem to add anything substantial.
The 3D graphics were neat, but the main room being on an angle was distracting in a strange way. That might just be me.
The concept definitely deserves more exploration. Good work.
