Something as simple as generating an ssh key pair and using it for authentication leaves them completely bamboozled. By their questions it is clear that most haven't bothered to learn anything about it.
They don't care about security, performance, best practices, or anything but completing their problem sets and projects and getting their degree.
I don't understand the thinking in getting into a career field that you have no intrinsic interest in. And how they think they are going to get past even a half-hearted technical interview is beyond me.
