FOUNDING STORY

It started with an interview
I needed to prepare for.

A real deadline. A simple need. The beginning of Inquisitor.

When I had the opportunity to interview for a new role, the team was hiring quickly, and I had little time to prepare. Finding someone with the right expertise and time to help proved harder than I expected.

I searched for mock interview services, but the options I found required months of commitment and thousands of dollars, or were already booked out. I wanted something simple: a realistic interview and feedback tailored to the level I was interviewing for.

So I started experimenting with AI, piecing together different tools to practice. It helped, but getting everything to work took a lot of effort, and the experience was inconsistent.

That experience inspired Inquisitor: an interview prep platform built to recreate the real interview experience, with the practice and feedback to help you ace your next interview.

Build confidence with every interview.

The interview isn’t getting easier. You’re getting better.
