To each his own I guess. When I find time to get on those hackerrank type sites, I find the algorithm practice and refreshers to be both enjoyable and time extremely well spent in terms of maintaining fundamental CS skills. It doesn't matter if my job doesn't have me implementing graph algorithms every day, it affects the code I write (and decide not to write) all the time. Learning how to weld a few 3rd-party APIs together just isn't enough to be a truly good professional.
