The Danger Zone: Top Reasons Candidates Fail
Based on our database of SNCF interview outcomes, avoid these common traps:
- Suggesting solutions that are not scalable or adaptable to different urban environments.
- Describing a task that was clearly assigned to them.
- Generic answers about 'loving trains' or 'wanting to work for a large company'.
- Focusing only on one part of the supply chain (e.g., only warehousing) without considering the end-to-end flow.
