I agree about standardization but unfortunately for lazy / hazing start-up types and for big bureaucrat types this converges to dumb shit like HackerRank, which (short, high time pressure, commoditized trivia) is close to the precise opposite of what matters in a candidate.

HackerRack / IKM / etc do not qualify as the good version of standardized interviewing. Use of such tools speaks loudly of hiring dysfunction.
