The Danger Zone: Top Reasons Candidates Fail

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

Jumping to solutions without a structured diagnostic process (e.g., immediately suggesting more inventory without understanding why it's not flowing).
Suggesting a one-size-fits-all inventory policy without considering product attributes (e.g., fast fashion vs. basics).
Giving a generic answer about e-commerce growth without mentioning Trendyol's specific context.
Not discussing the feedback loop between forecasting and inventory management.
