Most “prep calls” are pep talks. This is a dry run. I work as a senior frontend engineer. I have shipped production UIs in React and TypeScript: messy data, real-time views, the gap between localhost and prod. I use that for mocks, not for talking about my day job. Book a 45-min frontend mock if you have a loop coming up. You get live React + JS questions, one UI system-design prompt, a straight score, and a 1-page notes file after. What was strong. What failed. Three things to drill this week. Who this is for: - Mid and senior frontend engineers - People who can code, but freeze when the interviewer says “design this UI” Who this is not: - A job offer, referral, or resume rewrite - Help with your current employer’s codebase - A beginner “what is useState” class If you want a calm, honest practice session before the real thing, book the mock. Come with a JD or just say “senior frontend, product company.”
