Seriously. Here is how to do it.
I'm looking for a React Developer, I ask the following simple questions:
1. Tell my about your contributions to major projects you have been involved in. (if they share their work ask more in-depth questions about it)
2. With $givenTechnologyStack, how do you usually solve state management / routing / styling / responsiveness / SEO / performance / security / validation...?
3. Why do you think, concretely, that you can help solve our problem?
Any experienced interviewer will know by the answers if they're dealing with a pretender or the real deal.
Edit: I know recruiters don't have in-depth technical knowledge they should simply forward the few interesting candidates to tech. If you have time for 5 rounds of nonsense you have time for 1 round of quality interviews.
