I don't think mcjon was suggesting that interviews for technical positions frequently veer off into discussions about literature.

Rather, I think the experiences you are "supposed" to get in a traditional 4 year university education - such as discussions about literature and other topics not directly related to your degree - are widely believed to improve your ability to think in ways that perhaps aren't directly quantifiable, but nevertheless provide significant benefit to your employer.

These benefits can manifest, for example, in employees that are able to handle disagreements among themselves rather than running to their manager every time they butt heads. Or employees that are simply able to learn new systems without extensive hand-holding through every step of the process.
