Interview Solver
Interview Solver is a desktop interview copilot built for live coding and system design rounds. It runs on macOS and Windows, stays invisible during screen sharing, and delivers real-time LeetCode solutions, flowcharts, and syntax-highlighted code while you work through problems on HackerRank, CoderPad, or a shared IDE.
The app uses global hotkeys so you can capture a screen window, transcribe system or mic audio, or query selected text without alt-tabbing. Training data covers the full LeetCode question set, and companion mode lets a second device display answers or bring in help from someone off-camera.
Software engineers preparing for FAANG and other technical screens use it when they need backup during live interviews. Bootcamp grads and candidates returning to the job market after time away from coding rounds are a core audience, with the site citing trust from over 10,000 engineers.

Can Interview Solver be detected during screen sharing?
Interview Solver is designed to stay invisible to screen sharing on Zoom up to version 6.16, browser-based recorders, and Activity Monitor or Task Manager. Global hotkeys are registered at the OS level so browsers cannot detect the key combinations.
