TypeScript
TypeScript interview drills covering the parts senior engineers actually probe — type narrowing, generics, mapped/conditional types, utility types, module config, and the runtime-DX layer (decorators, type guards, satisfies). Fresher basics through staff-level type-system design, all at your pace.

Why this matters at interviews
Real interviewers don’t just check if you know the syntax — they probe whether you’ve used the concept under production pressure. Our drills mirror that. Adaptive difficulty, named anti-patterns called out as you go, and a senior-staff voice that teaches the production vocabulary rather than dumbing it down.
