That willingness to prepare doesn't reconcile with the realities of parenthood and all of the other responsibilities someone in their thirties may have. Consistently finding that time will be a huge ask, especially if you haven't worked on those problems in a while.
I mean, it would be illegal for them to state it outright, but most companies would prefer not to hire people with kids and other responsibilities. That's the whole reason there are specific discrimination laws for that.
LeetCode questions neatly solve the problem of not wanting to hire people who won't, or can't, spend hours of their free time doing things they hate for a goal they don't care about except to the extent that will feed and house them.
