I ended up doing much of the grunt work for them (it's a small operation).
The firm hardly believed in computers to simplify things so they had me do many things outside of modeling through paper records and I was essentially one of 3 "slaves" as the execs liked to call us with not much humor to the tone.
Perhaps commensurate with the pay but generally excessive, the execs demanded absolute focus at all times and punishment was harsh. A poor intern in his third year of a good uni with great prospects was sacked for playing solitaire! If there was nothing to do because all our analysis for the day was done, we'd be expected to read the Financial Times (in print, not on our terminals) and if you had already read that day's issue then no problem - there is a rich physical archive of past issues for you to "backtest your ideas"!
