Re: confidential terms
AC, you must be a pom or merkin. When I started in IT most of the older staff went out of their way to induct me into the folklore and wisdom/bitter experience of their times. That meant my newbie status was far shorter and the wiles of sales weasels much less effective. As I became one of the old timers I enjoyed mentoring the bright young things failed by the assembly line excuse of an IT degree so they became useful quickly. And yes, that was successful.
Some things like skepticism, proper cost/benefit analysis and assuming senior manglement always lie or are deluded just have to be learnt on the job. Yes there are IT knowledge hoarders, but usually those were outnumbered by adults.
