I agree that a good interview process should check that the applicants have their bases covered with algorithms and data structures. I agree that having a compendium of good questions to ask for this purpose is useful. And I agree that HackerRank and LC have compendiums of such questions.
However, I disagree that that makes HR or LC valuable or a positive in the interview process. Basic DS and Algo questions do not require the types, number, or complicated questions one finds in HR or LC. Such questions are easy to come up with and test, and should be a notable, but minor part of the interview process.
HR and LC take what should be a minor (though important!) part of the interview process, and blow them to huge proportions, and thereby distort and harm the very process they're supposed to be helping. They do this, in an attempt to present themselves as having a larger value add than they actually do.
