There are two things to measure - ability to get an offer (easy) and effectiveness on the job (hard). Triplebyte has clearly provided an improvement on the former. Seems like the latter is very difficult to measure, but I don't know why anyone would assume quantifying would negatively correlated with performance - at worst one might assume it is not correlated.
