You don’t want to hire boring bot-like people, but you also don’t want a totally subjective hiring system full of bias. I think having an objective scoring of some sort is a good reference even if it’s not the final decision.

This is full of bias and the bias is the experience and personal opinions of the person who created the matrix.

Here’s the thing: there is precious little if any empirical evidence suggesting that what is objectively measurable (e.g. solutions to textbook CS problems) has utility as an indicator of engineering competence. There are exceptions of course, for example in roles requiring a person implement such things as for a library, but these aren’t the rule.
