LeCruiter AI

An interview-practice tool we built at an AWS hackathon. It generates contextual questions and returns feedback on what you said and how you delivered it.

01

Practising the answer and the delivery

We built LeCruiter AI at an AWS hackathon as an interview-practice tool. AWS Bedrock generates questions in context and evaluates the content of the response. A separate pass analyses tone and sentiment, giving the feedback two distinct views of the same answer.

02

The practice loop

The React interface presents a question and lets the user record a response; a Python backend built with FastAPI connects that interaction to the model. The behavioural prompt and coding view below show the practice formats we built around that loop.
