I couldn't always get people to talk this way, but people who did usually worked out well
This is really the same issue with the promo culture we see at Big Tech companies: you end up promoting the people who are good at crafting promo packets i.e. telling stories about their work. There is certainly a good overlap between that and the people who do genuinely good work, but it's not a perfect overlap.
Personally I don't really mind it because I consider myself good at story telling. But as an interviewer I would never do that to a candidate because not everyone can tell good stories.
