That part about "write down the question" and the "what are you looking for" is a rather important part that most people ignore and just wing it.
By having that rubric down it becomes easier to make the objective choices (that can be backed up with HR). Additionally, that same question (with the same rubric) can be used by other interviewers for other candidates and overall, you would hope that the same candidates would get the same thumbs up / thumbs down evaluation no matter who asked the question or considered them.
