I applied online. The process took 4 weeks. I interviewed at Boston Consulting Group (London, England) in Feb 2016
Interview
Everyone was so friendly and made sure you were completely at ease. I had two 1:1 interviews with project managers - both interesting case studies but ultimately my maths let me down.
At the beginning of each interview they also asked competency questions - these were basic and put me at ease.
Multiple rounds with consulting case interview portions and fit portions. Each round of interviews had multiple interviews, and the interviewer gets more senior as you progress through the interview process
