@Fozzie You reminded me of a guy I briefly worked with when I was a teenager.
I worked for an ICT company supplying networks and support to schools( I'm old so we are talking Windows NT, 98se, 2000) My job was office based. Building the machines and repairing any that the engineers couldn't do on site.
A new engineer was hired, ex IBM guy so everyone was expecting big things when he came in. Turned out the annoying little 19 year old prick who spent most of his time in the office downloading music from winmx and had no formal qualifications.......in other words me ..... knew a shit load more than he did
It came to light that all he used to do at IBM was go on site, load a norton ghost recovery image and say " there you go " and if that didn't work he took machine back to office to let someone else fix it
