Node.js test for interview: free practice with answers
What a Node.js screening round looks like, five sample questions in the same style, and the full free test with every answer explained.
What the real round usually looks like
Most Node.js interview tests are ten to twenty multiple-choice questions, sometimes followed by a short practical task. The pass mark is 80%, and this skill is commonly screened for back-end developer, Node.js developer, API developer and full-stack roles. Requirements vary by employer, so treat the benchmark as a floor.

Common questions
Do the questions use CommonJS or ES modules?
Both appear, because real projects use both. Each question states the module type when it matters, so read the package.json detail carefully.
Is Express the only framework covered?
Express is used for routing and middleware questions because its model is simple and widely known. The ideas of ordered middleware and central error handling carry over to most Node frameworks.
Do I need to know Node internals like libuv?
Not in detail. You should know that your JavaScript runs on one thread, that slow input and output happen in the background, and in what order callbacks come back.
