Applied during career fair and received a phone call a month later. First round not to complicated ; questions about forwards and options. Second and final round in London : I saw the head of the team in person and the other members of the team by videoconference (since the job was in Paris) : more questions about options ( more difficult: binary options mostly) and greeks.

I had mainly fit questions and almost no technical questions. Mostly background questions and situational questions. I was only interviewed by the manager of the team during thirty to forty five minutes who explained how the team was built and the daily workload that will be expected.
