Dear Andy,
thank you so much for your insight!
to be honestly, I really have no idea which direction I should be heading.
the only IB experience I have so far was an interview with Gyan's team in bears back in 2007. I was lucky enough to get an offer but didn't take it.
I have no PHD degree and don't know C++. However, I am very good at statistical computing and willing to learn anything new that is necessary to get into the door of IB.
