The Electrical Engineer at the firm tells a story about the Engineer at his school that was recruited by a major auto manufacturer as an intern straight out of college (before graduation) ... which was very prestigious and something students dreamed about. Thirty years later, he is an expert on the design of Glove Boxes and goes to "Glove Box" trade shows and conventions to keep up on the latest innovations.
How is that for hyper-specialization?
They actually warned me about that in Architecture School. A professor cautioned that if I went to work for a large firm immediately after graduation, I would end up given a specific task and would learn nothing except that task ... I would be the person that did Restroom Specifications for all the giant skyscrapers, or I would be in charge of the stair details and making sure they met local code (and nothing else).
It occurs to me that this has Traveller applications for "house rules" ... LARGE organizations (like a Megacorporate MERCHANT or Imperial Navy), should retain characters in one position gaining high specialization in a narrow range of skills, while SMALL organizations (like a FREE TRADER or a Planetary Navy) need people to be exposed to a wider variety of activities and skills (more Jack of all Trade characters).
