The Danger Zone: Top Reasons Candidates Fail
Based on our database of Aircall interview outcomes, avoid these common traps:
- Not clearly articulating the 'why' behind the vision or strategy.
- Blaming the other person entirely without acknowledging their perspective.
- Focusing only on the outcome without detailing the influence process.
- Using a simplistic relevance score that doesn't capture nuances.
