my qualifications are all in chemistry / health & safety / dangerous goods handling / management skills but I seem to cope quite well with computer "troubleshooting"
If anything I've found in those I've employed that paper qualifications actually give little indication of an applicants ability for the job. Far more important is evidence of geekery - like does he build his own PCs? How much time does he spend online in his bedroom? Does he have a girlfriend ?(no = good) What does he eat (pizza = good, healthy diet = bad)
Nearly all good "troubleshooters" I've met have been self-taught, with long periods of reading Microsoft manuals and resource kits, but no formal qualifications. Conversely, those who actually have paper qualifications are as often as not a total waste of time: no practical experience.
Of course, what I'm talking about is very much at the low end of the feeding trough: home users, small / home businesses. Once you grow beyond that then things change a lot. You DO need relevant qualifications then
