Generics, conditional types, inference, utility types, and when to stop fighting the compiler — the questions that come up in modern frontend and Node rounds.
Sample questions
These are the kinds of questions you'll drill. Real mock rounds will generate many more — tailored to the exact JD you paste in.
What's the difference between `interface` and `type` — when would you pick each?
Explain how generics improve a function you've written.
What are conditional and mapped types useful for in practice?
Have you ever had to reach for `any`? What did you do instead?
Reading TypeScript questions isn't the same as answering them live. You need the rep — the pause, the clarifying question, the moment where you realize you forgot the framework. We put you in that exact spot, then show you what a strong answer would have looked like.
