I applied in-person. The process took 4 weeks. I interviewed at MyLotto24 (London, England) in Apr 2012
Interview
Initially, I was given a week to complete a computing task related to the company's domain of application. After having completed the computing task, I attended an on-site interview. During the interview, I was asked general background questions as well as technical questions in the form of elementary statistical exercises.
