The Danger Zone: Top Reasons Candidates Fail

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

Focusing only on distance minimization without considering delivery windows, vehicle capacity, or traffic.
Not clearly articulating the 'before' and 'after' state of the process/product.
Presenting a situation where no real trade-off was involved.
Not considering the trade-offs between resilience and cost.
