Answer
Forgetting to initialize all fields. Frame the concept in practical terms so you can explain it during interview discussion.
A common mistake is not initializing all fields in a constructor, which can lead to unintended null values or default settings. In an e-commerce app, if a `Product` constructor doesn't set the `category` field, it might default to `null`, causing issues when displaying product categories.
