Difference between duplicating a page and branching in Figma

WHAT THIS TESTS: The interviewer wants to know if you understand the mechanical and workflow differences between page duplication and Figma branching, and whether you can choose the right tool based on project phase, team size, and release risk. This is about file hygiene, design ops, and preventing developer confusion.

A GOOD ANSWER COVERS: First, the technical distinction. Duplicating a page copies frames and layers into the same file, increasing file size and forcing teammates to hunt through multiple pages to find the approved version. Branching creates an isolated copy of the entire file that does not alter main until you merge, and Figma provides a before-and-after diff view. Second, the governance distinction. Duplication has no review gate; anyone can edit the copy and there is no formal merge process. Branching supports assigned reviewers who must approve changes, mirroring Git workflows. Third, when branching wins. It is superior on active projects with deadlines, multiple designers, or ongoing development handoff, because it guarantees that main contains only approved, production-ready work. Fourth, performance and maintenance. Over time, duplicated pages bloat the file and slow navigation, whereas branches stay isolated and can be closed or merged cleanly.

COMMON WRONG ANSWERS: Saying branching is just for large teams or that duplication is faster for quick experiments misses the point; even solo designers benefit from branching when developers rely on the main file. Claiming that duplicated pages are safer because they are visible is a red flag, since visibility without version control creates overwrite risk and file bloat. Another red flag is ignoring the review workflow entirely, or suggesting developers should check multiple pages to find the final design.

LIKELY FOLLOW-UPS: How do you handle merge conflicts in Figma when two designers edit the same component? What naming conventions do you use for branches? How do you keep developers from accidentally shipping exploratory work? At what team size does branching become mandatory rather than optional?

ONE CONCRETE EXAMPLE: At DECODE, once a project leaves the earliest discovery phase, branching becomes the default for any meaningful change. A designer creates a branch to explore a new checkout flow, assigns a frontend engineer and QA as reviewers, and iterates without touching main. When approved, the branch merges into main, sending a clear signal that development can begin. If the team had duplicated a page instead, the file would accumulate outdated explorations, developers would struggle to identify the approved screen, and the risk of shipping unapproved work would rise significantly.
