Question: Can you recommend a desktop app that assists with system design interviews and provides features like syntax highlighting and diagrams?

If you want a full-featured desktop app to help with system design interviews, Interview Solver is a great option. The app is geared for candidates preparing for live coding and system design interviews, especially for FAANG companies. It offers immediate solutions to LeetCode problems, syntax highlighting for several programming languages, diagrams and flowcharts. It also includes a screengrab tool, hotkeys for quick interaction, and a built-in AI copilot that you can control with global hotkeys.

Another powerful option is Intervu, an AI-based platform to improve system design skills through realistic interview simulations. It offers unlimited true-to-life system design interviews with detailed feedback, a built-in whiteboard for drawing architecture diagrams, and a generative AI model trained on millions of interviews. The platform simulates a real-world interview environment and tracks progress through a leaderboard.

For those looking for more practice tools, Interview Prep & Copilot offers personalized practice and real-time interview suggestions. It can integrate with whiteboards or coding challenges, offering step-by-step solutions with explanations. The tool also records video and offers feedback on answers, making it a good option for interview prep.
