Precisely what you did in a previous job
Question
Pick a role listed on your resume and explain exactly what your responsibilities and contributions were.
Short answer
Be specific about your own contribution, not the team's. Describe the problem, the tools and methods you used, decisions you made and the outcome, with numbers where possible. Expect follow-up probing, so only claim what you can explain in technical detail, and be candid about what others did.
