How do I describe a group project and make my role clear?

Mention the team size, then focus your bullets on the parts you personally did. Readers want to know your contribution, not just the team's result.

Example:
"Retail Demand Forecasting | Business Analytics capstone | Jan – May 2025

• Team of four; I owned data cleaning and the forecasting model.
• Built a time-series model in Python that predicted weekly sales for 20 products.
• Presented findings to a panel; project graded A."

Use accurate verbs: "led", "designed" and "built" for your own work, and "contributed to" or "supported" for shared work. Be ready to explain your part in detail at interview.

If the team divided work by area, say which area was yours: research, design, coding, analysis, writing or presenting. If you also coordinated the team, add a separate bullet for that. Avoid writing "we" in bullets, and do not list the team's total output as if it were yours alone. A clear, modest description of a real contribution is more convincing than a claim to have done everything.
