You have to experience working in an IB to appreciate the article. They are very very much swamped down in politics process and paperwork (albeit electronic these days). It takes ages to do small things, forever to do the rest. No one has a long-term view beyond the next quarter, and most believe in doing just enough to grab some bonus and run. You will encounter big swinging dicks who like to lord it over the interns, making them stay late, just because they can. You will see many many unhappy faces everyday, and you will feel a little bit more lost with each day you remain there.
