Codemia provides an interactive platform for preparing system design, data structures, algorithms, and object‑oriented design interviews. Users can solve 120+ design problems on a collaborative whiteboard, receive AI‑powered feedback and editorial solutions, and track progress with spaced‑repetition flashcards and leaderboards. The service also offers mock interviews with real engineers, live video calls, and peer feedback to simulate real‑world interview scenarios.

Problem
Many software engineering candidates rely on passive study methods—reading articles or watching videos—to prepare for system design interviews, which leads to poor retention and insufficient hands‑on experience. Without interactive practice and real‑time feedback, candidates struggle to demonstrate scalable design thinking during actual interviews.
Solution
Codemia offers an interactive, web‑based platform that lets candidates practice system design, algorithms, and object‑oriented design problems in a hands‑on environment. Users work through over 120 curated design scenarios using a collaborative whiteboard while an AI engine evaluates their solutions and provides instant feedback on requirements coverage, scalability, and trade‑offs. The platform incorporates spaced‑repetition flashcards and SM‑2 scheduling to reinforce key concepts and improve long‑term retention. Additional tools include visual step‑by‑step algorithm visualizations, UML diagram generators, and mock interview sessions with live video and peer collaboration, enabling candidates to simulate real interview conditions.
Target Audience
Codemia targets software engineers preparing for technical interviews at mid‑size to large technology companies, as well as students and professionals seeking structured, practice‑focused training in system design, algorithms, and object‑oriented design.
