CV screen Take home coding task - code up a strategy from a mathematical description. Technical interview call with questions and live coding in Google doc. After the technical interviews I was told that I had passed and an in person final round interview with the company founder was scheduled at their London offices. Three days before I was due to travel for the interview, I was told that the company needed to reschedule. They declined to schedule a new time for over a week, and then simply said the position had been filled. The company also refused to reimburse non-refundable travel expenses which I had paid out of pocket.
