The Danger Zone: Top Reasons Candidates Fail
Based on our database of Mambu interview outcomes, avoid these common traps:
- Describing a situation that was resolved by simply giving in or avoiding the conflict.
- Describing a situation where influence wasn't necessary (e.g., the decision-maker readily agreed).
- Failing to consider the unique challenges of emerging markets (e.g., infrastructure, literacy, regulatory hurdles).
- Listing vanity metrics (e.g., 'number of users') without defining what success looks like.
