I think you're missing the point of the question. Qualified candidates have options. The question is why do they want to choose you over the other places.
This would’ve been a beautiful question if everyone only applied to one job, and this was a chance to tell the future you’d like to see and how you, the candidate, would build this future. But is that ever the case in practice?
It’s all a game.
I'm aware that I've been privileged to have options, but given that I do, I see no reason not to be honest.
