An engineering mindset and systems thinking—or simple awareness of things like experimental design principals—are badly under-applied to software hiring processes, IMO. "What are we trying to select for with this section of the interview? Does this accomplish that, or does it do something else, or does it accomplish that but also do something else? Are we being any less humane and supportive in this section than necessary to evaluate what we have decided we need to evaluate? If not, how can we fix that?"
