No, the interview was fairly vague and thus partly my fault for not getting a better description. To be fair, the other areas within that office were hardware related (setting up SANs, configuring and cabling them up) so had I stayed I would have learned that. I described it like this to friends who asked: what I wanted was "The Unix/Linux System Administrators Handbook", what I got was "Chapter 8: Storage" or even just the "Disk Partitioning" subsection of Chapter 8 of that book. ;)
