How to Answer — The STAR Method
Use the STAR structure to answer behavioural questions with a strong story:
- Situation: What was the context?
- Task: What was your responsibility?
- Action: What did you do?
- Result: What outcome/impact followed? (with numbers if possible)
What to Highlight in the Interview
- ✓Write every improvement with methodology + number: "changeover 55 min → 18 min with SMED".
- ✓Always state your Six Sigma belt level (Yellow/Green/Black Belt); employers look straight at this.
- ✓Do not just say "improved efficiency"; use measurable KPIs like OEE, OTIF and inventory turnover.
- ✓Highlight data-analysis tools (Minitab, Python, Power BI) — industrial engineering is increasingly an analytical role.
- ✓Write your ERP experience by module (SAP MM/PP) — far stronger than "I know SAP".
What to Avoid
- ✕Writing improvement projects without numbers ("improved processes" but by how much is unclear).
- ✕Not stating the methodology used (Lean, Six Sigma, DMAIC).
- ✕Skipping analytical-tool skills; writing only "Excel" and never mentioning Minitab/Python/Power BI.
- ✕Claiming "I did it" across production/planning/quality without showing depth in any.
Frequently Asked Questions
How should I prepare for an interview?
Study likely questions in advance, prepare a concrete example from your own experience for each (using STAR) and rehearse out loud.
How much should I talk in my answers?
Ideally 60–90 seconds per question. Too short seems disengaged; too long seems unfocused.
What if I get a question I do not know?
Be honest; say you do not know, but add how you would learn it or a similar experience. Making things up is the biggest mistake.
