SUN Mobility Sustainability Analyst Interview: Rounds, Questions and Preparation

What the job involves

A Sustainability Analyst in EV, cleantech and mobility tracks environmental impact, battery circularity, charging energy use and ESG metrics for electric fleets and swap networks. Day to day you collect data from operations and suppliers, calculate avoided emissions and carbon intensity, and help teams meet compliance and customer reporting needs. You also support grant applications, BRSR or ESG disclosures and pilot studies for new clean mobility models.

Role and technical knowledge

1. 1

   How would you calculate the avoided emissions from replacing 100 diesel three-wheelers with electric three-wheelers?

   Mention diesel litres per km, grid emission factor, vehicle efficiency and annual km. Show a simple formula and note assumptions like charging losses and grid mix.

2. 2

   What is a life cycle assessment for an EV battery and why does it matter for a company like SUN Mobility?

   Cover raw material extraction, cell manufacturing, use phase and end-of-life. Explain that LCA shows true carbon benefit and guides recycling or second-life decisions.

3. 3

   Explain the difference between Scope 1, Scope 2 and Scope 3 emissions for an EV fleet operator.

   Scope 1 is owned fuel, Scope 2 is purchased electricity for charging, Scope 3 is supply chain and battery manufacturing. Give a fleet example for each.

4. 4

   What are the main environmental and safety concerns in battery swapping and how can they be managed?

   Mention thermal runaway, charging safety, battery degradation and e-waste. Suggest monitoring, standardised packs, recycling tie-ups and proper cooling.

Practical scenarios and data

1. 5

   You have monthly charging data from 50 swap stations. How would you estimate the carbon intensity per swap?

   Describe data cleaning, kWh per swap, local grid emission factor and time-of-day variation. Mention using a dashboard and validating with sample station meters.

2. 6

   A client claims their EV fleet is zero emission. How would you respond with a more accurate sustainability view?

   Acknowledge tailpipe zero but explain grid charging, battery manufacturing and disposal emissions. Suggest a well-to-wheel or life cycle framing.

3. 7

   How would you build a simple dashboard to track monthly CO2 saved, energy used and batteries recycled?

   Name key metrics, data sources, refresh frequency and a tool like Excel or Power BI. Mention data quality checks and a clear baseline.

4. 8

   What data would you need to apply for a green financing or ESG grant for a clean mobility project?

   List baseline emissions, project emissions, monitoring plan, cost per tonne CO2 saved and alignment with Indian or international reporting standards.

Policy, business and sector awareness

1. 9

   How do FAME and state EV policies affect the sustainability case for battery swapping?

   Mention demand incentives, charging infrastructure support and local manufacturing. Explain how policy lowers cost and improves adoption, which strengthens emission savings.

2. 10

   What is BRSR and why would a fast-growing EV company care about it?

   BRSR is SEBI's sustainability reporting format for listed companies. Even unlisted firms may prepare because investors, customers and lenders ask for ESG data.

3. 11

   Compare the sustainability trade-offs between battery swapping and fixed charging for last-mile delivery fleets.

   Discuss upfront cost, land use, battery utilisation, grid load and battery life. Note that swapping can reduce downtime but needs standardisation and extra packs.

4. 12

   What metrics would you track to show progress on circular economy for batteries?

   Examples include collection rate, recycled content, second-life packs deployed, recovery efficiency of lithium, cobalt and nickel, and tonnes diverted from landfill.

Behavioural and HR questions

1. 13

   Why do you want to work in EV and cleantech sustainability rather than a general consulting or finance role?

   Connect personal motivation to measurable impact, mention a project or course, and show awareness of India's mobility transition. Keep it specific to the sector.

2. 14

   Tell me about a time you worked with incomplete data to reach a conclusion.

   Use a STAR example. Show how you documented assumptions, did sensitivity checks and communicated uncertainty clearly.

3. 15

   How would you explain a complex emission calculation to a non-technical operations manager?

   Focus on simple language, one clear number and a visual. Mention avoiding jargon and linking the result to cost or compliance benefits.

4. 16

   Where do you see yourself in two years in a growing cleantech company?

   Show willingness to learn battery data, ESG reporting and policy. Mention taking ownership of a metric or pilot and growing with the company's scale.
