The Danger Zone: Top Reasons Candidates Fail

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

Failing to segment inventory based on product characteristics (e.g., ABC analysis, shelf life).
Treating cost and service as mutually exclusive rather than interconnected.
Failing to consider the unique requirements of a premium product (e.g., packaging integrity, temperature control).
Underestimating the impact of marketing activities, promotions, or competitor actions.
