The STAR Method

┌─────────────────────────────────────────────────────────────┐
│  S - SITUATION                                               │
│      Set the context (2-3 sentences)                        │
├─────────────────────────────────────────────────────────────┤
│  T - TASK                                                    │
│      What was your specific responsibility?                 │
├─────────────────────────────────────────────────────────────┤
│  A - ACTION                                                  │
│      What did YOU do? (60-70% of your answer)               │
│      Use "I" not "we"                                       │
├─────────────────────────────────────────────────────────────┤
│  R - RESULT                                                  │
│      Quantify if possible (%, numbers, time saved)          │
│      What did you learn?                                    │
