The 5/3 interview structure is a format-driven STAR interview. You will be asked questions like: "tell me about a time when you accomplished something that you originally didn't think you could?" You must answer by describing the Situation, the Task that was undertaken, the Action that you took & then the Result of all of that. The more quantifiable answers that you use, the better. E.g. I worked for XYZ bank as a personal banker. We were asked to achieve a sales goal of $X, which was twice last year's goal so I didn't think we'd be able to do it. I researched the tools made available to us by Marketing and discussed using the ABC plan to increase our customer cross-sell ratios at the team meeting with the other PBs and the Manager. We changed the plan a bit so that everyone was bought in. We implemented ABC plan with some extra effort during [whenever] because of [whatever]. We all worked some overtime to chip in, but to keep overtime to a minimum, we [did whatever] so that we could respect the team's work life balance. At the end of the year we exceeded goal by 10%. We were the only branch to even hit goal that year, as the typical branch was at 80% or lower to goal. We wouldn't have been able to do it if we hadn't come together as a team. Gaining the intial buy-in to the Plan as well as the excellent leadership and support provided by our Manager was what made all the differenence.
