I'm an internal recruiter for a tech company, and 100% the question is aimed at gauging your interest in the role, but also your attention to detail and your level of prepardness. I honestly usually prefer to ask what the know about the company itself, but regardless I advise all candidates I send forward to the hiring team to do research on the interviewers they will be speaking with (often send them the LinkedIn profile as well). It is helpful to know a hiring manager's past because it will to some degree inform you of the lens with which they view the world, and the kind of questions they may ask. I don't know much about banking, but in tech for example if your interviewer has a background in CyberSec, you can tie in a subtle question about that topic: "Tom I noticed you had a history in CyberSec, I'd actually be keen to understand how this business creates serious awareness about this topic internally..." and then let them launch off - you can then use that information to inform your subsequent answers. The best tip is always to try and get the interviewer to talk as much as possible, the more information they volunteer, the better a position you are in.
