The Danger Zone: Top Reasons Candidates Fail

Based on our database of Mylight150 interview outcomes, avoid these common traps:

Overlooking critical factors like local labor availability, regulatory compliance for energy infrastructure, or proximity to raw material suppliers.
Focusing solely on personal career growth without demonstrating an understanding of the company's impact or the industry's complexities.
Focusing only on transportation costs and ignoring other critical factors like warehousing costs, labor, taxes, and proximity to customers/suppliers.
Not accounting for the specific degradation characteristics of battery materials or implementing robust inventory tracking and rotation systems.

Test Yourself: Mylight150 Interview Questions

Three questions from the Mylight150 bank.

Type · behavioral

STAR

Tell me about a time you had to influence a cross-functional team (e.g., engineering, sales, finance) to adopt a supply chain strategy or change that they were initially resistant to. What was your approach, and what was the outcome?

Type · case-study

We are considering expanding our battery manufacturing facility to a new region to reduce shipping costs and lead times to the West Coast market. What key factors would you analyze to determine the optimal location for this new facility, and what are the primary supply chain risks associated with such an expansion?

Type · scenario

We are seeing significant discrepancies between our forecasts and actual sales, leading to both stockouts of critical components and excess inventory of others. Describe your approach to improving our Sales and Operations Planning (S&OP) process to better align supply with demand.
