Begin with the person and the problem

Introduce the intended user and the task your project supports. Describe your own contribution, especially if you worked in a team. This gives the interviewer context before you discuss implementation.

Walk through one meaningful decision

Choose a specific tradeoff: how you organized data, handled a failed request, or simplified a confusing screen. Explain the alternatives you considered and why you chose your approach. A concrete example is easier to assess than a list of framework names.

Be honest about what did not work

Describe an obstacle, how you investigated it, and what changed. If something remains incomplete, say so and explain your next step. Knowing the limits of your work shows care and self-awareness.

Practice a short walkthrough

Prepare a concise overview, then be ready to go deeper. Check the demo beforehand and keep screenshots as a backup. Invite questions and listen carefully. You do not need to know every answer; explain how you would find out.
