Lol idk if you’ve been doing this stuff for 20 years you’ll have those skills ¯\_(ツ)_/¯
More than likely someone with this sort of technical capacity doesn't score well in other areas.
But if this is built over 5+ years by reading, doing and learning from others and teaching others while understanding what level of abstraction/detail meets the current and future business requirements reasonably well, it's not that difficult or rare.
