If you were our first Sustainability Manager, what would your 90-day plan look like to build a credible sustainability strategy aligned with our business?
Employers ask this question to assess your ability to prioritize, create structure from scratch, and tie sustainability to growth and risk. In your answer, outline discovery, quick wins, and a roadmap with clear owners and metrics tied to company OKRs.
Answer Example: "In my first 90 days, I’d run a rapid materiality and baseline assessment, meet all functional leads, and map sustainability to revenue, cost, and risk drivers. I’d deliver a lightweight roadmap with 3-5 quick wins (e.g., Scope 2 reduction, customer-ready ESG FAQ) and a 12–18 month plan with owners and KPIs. I’d stand up basic governance (monthly ops sync, quarterly exec review) and a simple data schema to avoid rework later."

Can you explain Scopes 1, 2, and 3 emissions and how you’ve measured them with imperfect data at a small company?
Employers ask this question to gauge technical fluency in GHG Protocol and your pragmatism with limited resources. In your answer, define each scope and describe practical methods like spend-based factors, supplier estimates, and iterative refinement.
Answer Example: "Scope 1 is direct fuel we burn, Scope 2 is purchased electricity, and Scope 3 is our value chain. I’ve started with spend-based estimates for Scope 3 (using EPA/DEFRA or EXIOBASE factors), utility bills for Scope 2 with market- and location-based reporting, and any on-site fuels for Scope 1. Then I improved fidelity over time via supplier surveys, activity data (e.g., kWh, miles, kg shipped), and top-down to bottom-up triangulation."
