I'm a software consultant with a consultancy that would qualify as both high paying and remote in the UK and involved with interviewing, personally I value having a "homework" assignment so that candidates can complete a simple assignment and then build on that in a pairing session.
I don't think much of leetcode assignments as they tend to focus on the algorithm and getting solution through rather than writing good quality code that keeps it simple and is maintainable. That is much much more important than repeating an algorithm.
Though I also would say that in the current climate, the pressure on finding good candidates is so that a lot of places are considering dropping take-home tests in fear of putting off quality candidates, so I think you may well be in a good position at the moment to avoid leetcode and hackerrank...
