How to Pass the Decathlon Supply Chain Interview in 2026

The Decathlon DNA (TL;DR)

Decathlon values passion for sport, customer-centricity, and a proactive, entrepreneurial spirit. They seek candidates who embody their mission to make sport accessible, demonstrating teamwork, autonomy, and a drive to innovate within their retail and product ecosystem.

English original + your local-language translation

Tech and global multinational interviews are most often conducted in English. For industries like luxury, finance, or pharma, the working language may be local. We show every question in English first — alongside your local-language translation — so you can prep in whichever language your interviewer ends up using.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Decathlon interview outcomes, avoid these common traps:

  • Failing to articulate their specific contribution and impact.
  • Failing to articulate the impact or learning from the experience.
