Cognao AI

What it does

We built AI interviewers that conduct realistic interviews. This would help practise and conduct interviews. Currently, its for SWE roles, so it mimics an interview for the same. Its not like a QA agent that asks you fixed questions on JD, but its more dynamic. We built a custom video meeting platform with integrated code editor. The AI interviewer not only asks question about SWE and resume but also throughly examines candidate's problem solving skills by asking several DSA questions (need to code the solution as well, if you get stuck no worries, interviewer will give you hint!).

We recently finished our first phase of beta testing with actual customers and the feedback was good. Just a couple week ago we launched our first public beta.

The product is currently live at https://cognatoai.com. If you need any help to setup or run the product or see it in action feel free to connect with me. We are not providing 1 microservice which is crucial to run the application.

We used a hierarchical multi agent approach to build this. We tested out several LLMs to power this but finally settled with Gemini 1.5 Flash, Gemini 1.0 Pro (tried Gemini 1.5. Pro which did give amazing results but its rate limit was too low) along with Llama family (on Groq). Yes! we used them all, we put large models (gemini 1.5 flash and llama 3 70) to reasoning cases (things like decision making) and generation was done by 1.0 pro and llama 3 8b, this helped us significantly reduce interview costs.
