Marshall Wace Technology Graduate Programmer interview questions

I took a codility test after speaking with a recruiter over the phone at Wiser. From there took a problem solving lab test and spoke with a junior developer for 30 minutes. I then did a group exercise and spoke with HR. I progressed to project stage and was invited to a final round on site in London. Found all the staff at these stages very friendly and very interested in me. Decided to accept a offer at another hedge fund after my onsite interviews as felt the other firm offered a more focused role but the rotational nature would suit others but I know what I want to do full time.
