Depends upon the context, assuming you are refering to positions within a consulting firm.If so expect it will be like most analyst roles, research, interviewing, market analysis, modelling etc.Within industry it can mean something very different. I recently recruited 2 strategy analysts into the function I work in as a manager.They are involved with development of strategy, major M&A deals and working with the board on delivery of key projects. Advice would be to make sure you explore the role in detail before interview, then ask questions from an informed points of view (e.g. not "what would I be expected to do?" more "what is the balance between desk based research and client interaction")
