Had a Skype interview as the offices for Dalberg Data Insights is in Brussels and I am in the UK. The interviewer was really nice and quite casual. For the first 20 mins he told me about the company and what they do there, and more specifically his own role. Then let me ask some questions about the projects they were working on. Very informative! Next 20 mins he asked me about myself - my interests, why I wanted the job, why I enjoyed coding and the experience I had in the area. Final 20 mins he asked me a logic question to see how I dealt with data, which went well and is in the question section of this rating. Unfortunately, due to Brexit they were not sure whether they would be able to hire me because I was applying for a position in 8 months time and there was too much uncertainty, but they did say to contact again closer to the time, and that the interview had gone very well. They also said that they always hold two interviews by different members of staff so that they can make a balanced judgement about hiring.
