Yeah my roommate right after college worked at a major investment bank and the “culture” struck me as purely abusive hazing...he worked 6-7 days a week and was out of the apartment before 8am and home after midnight most days. The working environment he described sounded godawful...cruel for the sake of being cruel. Assignments delivered at midnight and due at 7am. People using the strict hierarchy to make junior people suffer. Young people with serious stress-induced health problems. Heavy drinking on the occasional night off to dull the pain.
