Hopefully by less lazy interviewing tactics and trying to hire via nuanced understanding of candidates instead of hackable metrics like memorizing leet code.

The traditional engineering interview is more fuzzy and is basically an engineer asking you about how you'd solve a problem they are currently working on or recently did. The interest is to see how you think and problem solve. It's inheritably unmeasurable but I think it is better than using a metric that ends up not meaning much. If it is explicit fuzziness vs implicit, I'll choose explicit every time because it is far harder to trick myself into thinking I'm doing the right thing when I'm not.
