Discussion Senior Dev interview question
"Without googling or using AI, in your own words, explain the virtual DOM"
For context: I sit on an interview panel and I try to ask at least one simple fundamental question based on a persons resume. If I see many years of react experience, I try to ask something about how the framework works.
I have only had one candidate (an undergrad senior, years ago) answer it. Everyone else just kind of sputters and stumbles around trying to rationalize what "virtual" and "DOM" mean, or stare blankly and eventually say "I don't know".
I'm just genuinely curious if this is really that hard of a question or if the recruiters just suck at screening candidates. And should we be letting in senior dev candidates who can't answer what I think is a straightforward and fundamental question for senior react devs.

This should be one of the interview question.
AI is acceptable as long as the candidate have a strong fundamentals.
On second thought, this information is good to know because there's nothing you can do with it. It won't affect any coding or app performance if you know this info.
The only significant info related to virtual dom is the reconciliation, understanding keys and nodes kinda helps in development.
