It's so backward to see companies shift to these abstracted whiteboard or homework assignments as some sort of standard, considering standardized testing is now falling out of favor in higher education as it is rarely indicative of actual potential success. It strikes me as lazy, just following a trend unrooted in any empirical data.

Maybe the solution is for companies to hire more thorough managers who are capable of vetting a github profile to see if the candidates skills are relevant to the position, not turn the interview process into a performance.
