Bankers don't want to know what you did (we can guess that from the title of your job), but they want to know what you learnt and achieved through your experience. Therefore, be results-oriented and use numbers. For example, do not write the all too common M&A internship description: "Performed valuation using DCF, comparables analysis, calculated WACC, and did benchmarking for associates in the group." Do write: "Led the valuation of a $700 million technology company under associate supervision, which involved building a complex operating model from scratch, full WACC analysis, and benchmarking of 25 companies in four countries." What is the difference? The good version gives more concrete details and clearly demonstrated the complexity of what you were doing. More interesting details will catch the banker's attention and also prove that you understand what you were doing. Note that this also works for any other kind of experience. Another example: Do not write: "Researched the consumer goods industry and helped partner writing industry reports." Do write: "Supported partner's analysis of the consumer good industry by identifying and benchmarking key performance indicators of 50+ retail companies across the UK."
