The Danger Zone: Top Reasons Candidates Fail

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

Blaming the other person or presenting the situation as one-sided.
Not considering the impact on downstream operations or customer service.
Overlooking factors beyond cost, such as lead times, customer density, and existing infrastructure.
Not considering the specific characteristics of different material types (e.g., cement vs. specialized aggregates).
