Next.js developer interview questions.
These prompts ask for a real example or a decision. They fit a recorded answer better than a live debugging session. See all interview questions.
Six questions for a recorded first round.
Add these prompts to a Hirekal interview and send the same set to every candidate. See interview workflows.

How to use this set in a recorded first round.
What should you ask in a Next.js developer video interview?
Ask one thing at a time, and keep each prompt short enough for one take. This set focuses on server and client rendering, caching, data fetching, and how a Next.js page stays fast.
How many questions should a recorded Next.js developer 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 Next.js developer candidate answer the same questions?
Yes, for that interview. The same prompts, in the same order, make the recordings comparable.
Can I add these Next.js developer 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.
