Your pocket interviewer, InPrepAI alternatives

Congratulations on the launch! Having worked in recruitment for 5+ years I really love the mission to help young professionals learn the ins and outs of interviewing. I've also seen many bright young people come into their first / second interviews answering simple questions in ways they should have avoided - creating massive red flags from the hiring managers causing them to lose out on the role. Question - Who are you consulting with for the question bank or is it something you've created internally?
