As perhaps the penultimate example of the meaningless of (and idiosyncratic requirement of) titles, at one point in a BigCo job I had a business card printer in my office and would print cards with the title needed for a given meeting. I didn’t have an official title at all; just a “grade level” for establishing compensation.
