Yeah, and all of those years are filled with constant punishment. In my experience it was common for medical students to have depression, severe anxiety, panic attacks before and after tests and exams. Binge drinking was extremely common after. At least two students committed suicide.

Definitely not something to be emulated.

Investment banks might not have been the greatest example here, many of them hire whoever under the auspices that while during incodtrination they work a play portfolio for free and those in the cohort who profit above a certain deviation and who can justify the strategy behind it get hired, the rest don't.

maybe they just don't understand the questions.

e.g: I challenge you to give an answer to my question?

it's such a simple question, how could anyone not give the right answer. but it's as badly communicated as your comment, subject to interpretation and perplexing.

now imaging being in a position of inferiority, in total fear to be asked about things you've never hear about before. like it happens not so rarely when sitting University in exams. you studied 90% of the curriculum for a year, but, bad luck, the exam concentrates on that 10% you've overlooked. you haven't prepared for a year for that interview, but it does feel like it while waiting in that soulless waiting room. The secretary bored to death nearby doesn't help gain any courage: she mastered the art of pretence, she isn't building some complex excel queries, she plays the solitaire. but you don't know that. and you haven't even entered the interview room yet.

if you don't picture that scenario, just try to give a speech on a very large audience. you will see how emotions can very well take full control over you.
