TrueCode is a full-stack web platform designed to help developers practice coding interviews together in real time. It allows friends, interviewers, or recruiters to create interview sessions where participants can solve coding problems collaboratively while communicating through video, chat, and a shared code editor.
The platform simulates a real technical interview environment, enabling users to practice solving problems, discuss solutions, and receive immediate feedback on their code.
Users can either:
- Upload their own coding questions
- Select a programming language and solve problems
- Input interview questions manually
- Upload a CV to generate interview-style questions
TrueCode aims to make technical interview preparation interactive and realistic.
