About MockMe.ai
Practice covers the complete interview loop: voice-based interviews with follow-up questions, an interactive architecture board where users sketch system diagrams the AI can see and respond to, and evidence-based feedback after each interview, including strengths, weaknesses, missed concepts, and actionable suggestions. The question library covers microservices, distributed systems, caching, load balancing, and designs for systems like Twitter, Netflix, Uber, distributed databases, URL shorteners, and notification systems.
Most mock interviews take 20 to 30 minutes with no strict time limit, and progress can be tracked over time across different areas of system design. The Interview Plan is a one-time payment with 30 days of full access to the question and drill libraries, and new accounts include one free 5-minute diagnostic with no card required.
