The Acerinox Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, operations background, supply chain interest. - 2
Round 2
Operations CaseEnd-to-end supply chain optimization, bottleneck diagnosis, network design. - 3
Round 3
Forecasting & PlanningDemand planning, S&OP, inventory optimization, working with statistical and ML forecasts. - 4
Round 4
OptimizationLinear programming intuition, route optimization, facility location, trade-offs between cost/service/CO2. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Acerinox interview outcomes, avoid these common traps:
- Not considering the impact on the existing network or total landed cost.
- Focusing only on minimizing distance or time, ignoring other critical factors.
- Providing a generic answer about supply chain without linking it to Acerinox's industry.
- Failing to adapt their approach based on the other person's concerns or perspective.
