Learn
Two things live here, and they answer different questions.
Jargon
Start here when a word in a job title means nothing to you. Every word a posting can throw at you, explained in two minutes, in plain English. Free.
The G2G library
Start here when you want the whole story: what the desk actually does all day, how the work is really done, and what the job is like. It is a book, From Greenhorn to Gold(wo)man, written by someone who did it. Most of it is part of membership; Jargon next door is free.

Next: the advisor tells you which of these matters for your year, and what has already closed.
