Interview guide
JavaScript interviews concentrate on the language's famous sharp edges — closures, the event loop, `this`, async patterns — plus practical DOM or Node scenarios depending on which side of the stack the role sits.
Closures and scope: lexical scoping, module patterns, common gotchas
Event loop: microtasks vs macrotasks, promise ordering questions
Async patterns: promises, async/await, error propagation
`this`, call/apply/bind, and arrow-function binding
Prototypes and classes: inheritance chains, instanceof
Practical rounds: debounce/throttle, deep clone, polyfill exercises
Be able to predict the output of event-loop ordering snippets (setTimeout vs promise resolution) — it's the single most repeated JavaScript interview exercise and quickly separates rehearsed from fluent candidates.

Directly — interviewers build questions from your resume's claims, so every skill and achievement listed becomes fair game. A tailored, honest resume steers the interview toward your strongest material; an inflated one hands the interviewer traps you set for yourself.
