It really depends on what kind of developer you're looking for. In the web applications I've worked on, knowledge of application architecture and experience with linux trumps anything I learned in a college course. Based on my experience, theory problems on white boards is about as useful as dropping a CUPs automation problem on unsuspecting interviewees. Build me a CUPs driver that drops pdf into in folder in 15 minutes or less. Without documentation. Bonus points if you can ask if you can skip that bullshit and install and configure an existing a package. Note: I'm a senior developer with at least a decade of experience. I don't just slap two libraries together. If you want to have fun, dig into how macOS sandboxes CUPs. My bash scripts were not happy.
