I had a first telephone interview with the Director of technology. It was 1 hour discussion about my CV and experience. No much technical question. A week later, I had another telephone interview this time with a Data Modeller from New York. We discussed technical questions about databases (index, data integrity, performance issues, etc.). A week after that second interview, I was invited to have a 1:1 interview at Trading Screen offices at London. I had two 1:1 interviews, of 1 hour each. Both interviews were shifting between technical questions and typical other interview questions (why Trading Screen?).
