They use a natual language AI model trained on a huge amount of data from the internet to generate questions and answers. This is a GPT-3 based model.

When Hirestack first built the generator, they were surprised by how insightful some of the questions were. They were specific to the chosen job title and indicated an understanding of what the job actually entails.

Hirestack thought wouldn't it be cool if we could also generate answers to the questions? The answers were nuanced and clear, many of them were answers we would like to see real candidates give.
