Has anyone ever had to reverse a linked list in "the real world" (tm)? Is that a singly-linked or double-linked? Can I use Google, which is what any sane developer would do in "the real world". I don't remember squat about data structs 301. So what. What does the typical developer do daily? I would be much more interested in how they approach bugs. What approaches do they use? Any tools they carry on a flash drive? What drives them crazy? What do they love? What are they learning?
