What the STAR method is
STAR structures behavioral answers into Situation, Task, Action, and Result. It keeps your story focused and ends on impact, what changed because of what you did.
Where to spend your words
Most of the answer should be Action, what you specifically did, with a quantified Result. Keep Situation and Task brief. The builder enforces that balance and tightens your notes into a deliverable answer.
Rehearse, don't memorize
Use the draft to internalize the structure, then deliver it naturally. Practice the behavioral and case rounds together for a complete interview.
