Coding assessments are largely used to filter unqualified candidates and save time. You can't reasonably interview every applicant, so you set a small barrier in place and those who can cross it get the time. Coding in interviews is more about understanding your logical decisions and brain flow, whether you ask the right questions or approach problems in a reasonable way.
Full disclosure, we still use hackerrank for just this internally.
I just think if a candidate scores a 70%, I don't expect them to be better or worse than a candidate who scores 100%.
Having criteria to perform an interview is one thing, but if your interview is just to go in with another toy challenge on a whiteboard, I think it would be much better to do a demo project, and immediately pair-program before making the decision to hire.
