How to use this set in a recorded first round.
What should you ask in a Node.js engineer video interview?
Ask one thing at a time, and keep each prompt short enough for one take. This set focuses on reliability under load, production incidents, slow dependencies, and how a Node.js service is structured.
How many questions should a recorded Node.js engineer interview include?
This page lists 6. You do not have to use every prompt. Pick the ones that fit the role, then ask every candidate that same set.
Should every Node.js engineer candidate answer the same questions?
Yes, for that interview. The same prompts, in the same order, make the recordings comparable.
Can I add these Node.js engineer questions to a Hirekal interview?
Yes. Create the interview, add the prompts, and send the link. Candidates record in the browser. Your team watches before booking a live conversation.
Do these video answers get an automatic hiring score?
No. The prompts are not a score. Your team watches or reads the responses and decides who moves forward.
Send the questions. Review the recordings later.
Candidates record on their own time. Your team watches the same answers before scheduling the next conversation.
