It’s well known in a specific setting, possibly? I’ve managed to never hear of it in 18 years. If asking “well known to some people” stuff is kosher, should I be able to quiz candidates on FFP design principles in Haskell, or maybe how to implement collision detection in a video game? Both of those are well known in swaths of the industry. I guess if you’re hiring for a specific role, writing OOP business applications, you will have no shortage of candidates who know about SOLID, but you’re probably passing on everyone who is changing domains.
