The key point for me is - what does the company value? Don't forget that you are interviewing the company too.
Does this company value grinding at solved problems, rather than actually solving new and interesting ones? That's a dead end. I'd rather talk about how I spent my time building real stuff in prod. That's generally how I respond to leet code challenges, pointing out the existing libraries and tools that already do it and discussing their tradeoffs. Pretty good way to find out they're looking for an actual engineer or a code monkey.
