How to Pass the Duffel Sales Interview in 2026
The Duffel DNA (TL;DR)
Duffel's core focus on simplifying travel APIs means interviews probe for your ability to tackle complex domains like "Flights Build" and "Search Book Ancillaries Order". They assess your capacity for structured problem deconstruction and delivering robust, scalable solutions, often through detailed discussions of technical decisions.

The Danger Zone: Top Reasons Candidates Fail
Based on our database of Duffel interview outcomes, avoid these common traps:
- Vague descriptions of pipeline stages without specific actions or criteria for moving deals forward.
- Underestimating the importance of IT and procurement in enterprise sales, or failing to engage them early.
- Focusing too much on technical features of the API without translating them into business benefits for the OTA.
- Describing an unresolved conflict.
