I did a mechanical engineering degree but have worked in computers ever since – all sorts of roles from programmer to project manager to solutions architect. I still put “programmer” on forms that ask for job. No relevant qualificationa.
My father-in-law had a HND than a degree in aeronautical engineering via Hawker Siddeley at Filton. He then became a travelling salesman for Shell because they offered a company car which was a step up from the motorbike and sidecar that he brought his son back from hospital in. No relevant qualifications but he did have the gift of the gab.
He ended up in tribology and management at Shell – Shell did pay for him to do an MSc for the tribology and even sessions at Insead for management. Shell was a pretty good employer in the 70s and 80s.
