User-needs approach

Do you think that an approach that consists of asking the user directly what their profile or sector of activity is and then refining the value proposition or directing them to a landing page that will aggregate the adapted solutions/expertise and other related content is a good practice or on the contrary does it show a flaw in the definition of personas and targets?

We sometimes see this principle on interfaces, so the idea is sometimes blown up by project managers and I have always wondered about the relevance of this practice.

You can take the section below the hero banner on this site in its French version to illustrate my point: https://www.bureauveritas.fr/

If I position myself as a user, I don't think I'd mind answering a simple question so that I'm well oriented. But I think that this already requires a minimum of commitment.
