For what it's worth, I currently work at one of the aforementioned software companies and my college experience is half a music degree. I didn't do any intense studying for the interview either, just spent a couple evenings doing project Euler problems in my favorite language to brush up as my job at the time was using different languages and didn't involve a lot of programming. I'm on the SRE/PE side of the world though, where I think interviews tend to line up with practical experience a little better.
