Collect evidence, not adjectives
“I am collaborative” is a claim. A story describes a situation, your action, and what changed. Build a bank before you memorize wording. Early-career and return-to-work sources can include projects, shift work, volunteering, coursework, and contracts when you can state what you personally did without inventing a result.
Use STAR or SOAR as a filing system
STAR means Situation, Task, Action, Result. SOAR adds Obstacle, which helps with questions about conflict, failure, ambiguity, or a stalled project. Neither is an employer rule. Spend most of a roughly ninety-second answer on Action and Result. For each story, write the situation, the constraint, your first-person action, and a result you can defend without making up a percentage.
Cover the thin categories first
Start with one story each for conflict, failure, ambiguity, ownership, collaboration, and learning. Label them in a few words so you can select a different story under pressure. Tell the weakest story once, identify the hole—too much setup, no result, no first-person action—change one line, and tell it again. Reuse facts, not a memorized paragraph.
