How would you set up version control for a small game team with programmers and artists?

What the interviewer wants to hear

• Use Git with LFS or Perforce for large binary assets
• Ignore generated folders such as Library, Temp, Binaries and Intermediate
• Use file locking for binary files that cannot be merged, like scenes and art
• Small frequent commits and branches or a clear trunk workflow
• Unity: force text serialization and visible meta files

Model answer

For a small team I would use Git with Git LFS, or Perforce if the art is very heavy. First, a proper ignore file so generated folders like Unity's Library and Temp or Unreal's Binaries and Intermediate never get committed. In Unity I make sure asset serialization is set to text and meta files are committed, because references depend on them. Large binaries like textures, models and audio go through LFS. Since scenes, prefabs and art files are hard to merge, I enable file locking so two people do not edit the same level at once. Programmers work on short-lived branches with pull requests, and we keep main always buildable, ideally with a CI build. Clear commit messages help when tracking down which change broke something.
