The Danger Zone: Top Reasons Candidates Fail
Based on our database of Air Liquide interview outcomes, avoid these common traps:
- Not connecting the LP formulation to the specific constraints of tanker routing (e.g., delivery windows, driver hours, tank capacity).
- Failing to quantify the impact or improvement achieved.
- Focusing solely on fulfilling the immediate order without considering broader customer relationship or long-term impact.
- Vague descriptions of responsibilities without concrete examples.
