To be fair, studying computer science isn't always indicative of knowing your way around tech anymore. I'm an undergrad in CS right now with some experience as a TA. The amount of people who got points off of submissions (for a 2nd year class) because they didn't know how to zip a folder correctly and submitted an empty zip file is honestly depressing.

That being said, even knowing what Linux is probably puts your tech literacy above most people so I doubt that was the case here.
