Used STAR method. i explained the overall project, i explained my specific role and the importance of it, i explained how i approached my task and why i did it the way i did, i explained the step by step actions i took to ensure the tasks were done correctly (such as creating a tracker on excel to manage my progress etc), i spoke about my findings, i spoke about the result and most importantly the impact of my result. oh and i also included something i struggled with because things aren't always perfect and i spoke about how i overcame the difficulty and still achieved my desired result.
