Hiring even developers with lots of experience but low conceptual skills has mostly been a disaster for me in the past. The same goes for "technical something" roles. Programming experience can be a bit of a red herring for those actually.
For the most part, my "technical" interviews go into conceptual skills and motivations. That's the stuff I really need to know to decide whether to hire someone. Some language/tool/framework, they can learn quickly, given conceptual skills, motivation and _some_ programming experience. (Disclaimer: I primarily hire generalists as FTEs. For specialist skills, I prefer to hire freelancers temporarily, where I focus on what exactly they can do today.)
