Went to two interviews and did a test but dropped out due to receiving another offer. First interview with HR recruiter was fairly standard. Second interview was by a data scientist who grilled me about all aspects of my CV and asked me questions about fraud analytics. Was tough remembering everything I had done on my Cv in so much detail but was actually a very pleasant and intellectually stimulating interview! Interviewer was very good at putting me at ease. Exercise was very interesting and should take about half a day. Expectations were to not overthink it and outline reasoning behind taking certain steps as well as explaining how I could have done things differently. Good insight in types of problems the company has
