Time to start asking more about security and OOP on interviews

OOP is kind of topic that everybody is expected to know, yet for some reasons there are huge gaps between people when it comes to proficency at it, at modeling systems and domains correctly.

Precisely because huge gaps exist, asking about OOP leads to disappointment. I don't suggest doing it -- or if you do, first try it out on coworkers (even just knowing what SOLID principles are, never mind any nuance about them), and if you're finding that it's filtering them, you don't work at an org where it makes sense to filter new hires the same way.
