The Danger Zone: Top Reasons Candidates Fail

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

Ignoring demand patterns and focusing solely on transportation costs.
Focusing solely on the per-unit cost difference without considering total landed cost.
Getting lost in mathematical notation or complex algorithms.
Not defining clear metrics or methods for identifying bottlenecks.
