what big questions! let me give a shot. The industry is EXTREMELY competitive and challengin, second only perhaps to investment banking. (i know this will cause noise). there are incredible opportunitiies to progress; usually if you start as a graduate in 6 years you will make manager ( 100-250K a year). Start salaries in london average around 30k, with some firms paying up to 46k (mercer) and some a bit less. a little advice though: dont enter this career because you did 'an interactive test'. be sure you understand what consulting is, what the life style / job entails etc before you go for it. it is an amazing career path, and will launch you into whatever you wish to follow if done correctly. good luck
