RUN can vouch that investment banks are known to hire local interns or fresh grads with average-results from non-banking backgrounds because gays tend to be very supportive of each other.
Intern? I think the son told her his salary was $12k and she mistook it for $12 a month. More likely $12k a YEAR. If that is the case, possibly true - they rather the $1k dude stay away from the real work.
One woman just proudly boasted to me, her son was accepted into GS bank as an intern for 12k each month. But due to some on going restructuring, no need to report for work. Just collect the salary each month. I told her the son is bullshitting her.
