The Danger Zone: Top Reasons Candidates Fail

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

Failing to consider the operational complexities and potential trade-offs of sustainability initiatives (e.g., cost vs. environmental impact).
Denying ever making a mistake or providing a trivial example.
Describing a task that was already part of their job description, rather than a proactive initiative.
Failing to articulate a clear connection between their aspirations and the role, focusing only on what they want to gain.
