I interviewed for Business and Services Summer Intern in London. First there was a short phone screening to find out more about the job. Next was an hour-long phone interview with a recruiter. Mostly behavioral questions and questions about background and CV. As a preparation I was asked to get familiar with the STAR method and think of particular examples that demonstrate top performance, people skills etc. After this was a Case Study interview with a hiring manager. This was many qualitative and quantitative questions based on an actual business case with numbers. This was slightly stressful as the manager rushed through the interview as if they were in a hurry. Next step would have been panel interview, but I didn't get to this stage. After the Case Study interview I was told that I made mistakes in my calculations and qualitative answers. Overall the interview was a positive experience. The recruiters were polite and were happy to provide feedback after every stage (this can help you in the future). Generally I would say that they are looking for very confident and qualified candidates.
