Bloomberg Developer interview questions

One phone interview after I applied online. Interviewer was nice and helpful. Question is interesting to solve. On December I was invited to the headquarter in New York where I attended two 2-on-1 interviews. I had difficulties to understand the instruction and wasted too much time at the beginning.

A significant portion of my interview was spent with the interviewer asking me about a trading system I had built, including details about the underlying algorithm and process. The details of his inquiries were inappropriate and were not relevant to the position I was applying for. Be very careful if you come to them with a good idea or something you have developed on your own.
