Shell Quantitative Analyst interview questions

The interview was 2 stages. First, my recruiter contacted me and asked some basic quesitons and made sure that I am the right candidate for the job. Then, I had an interview with a project manager. As far as I understood, this person was my line manager but in terms of admin, and project management. The technical line manager were the head of analytics, and traders who interviewed me in the second stage. The technical interview was quite casual and both of the interviewers were nice and made sure that I was not stressed.
