What inspired you to pursue a career in sustainability?

Working in sustainability is a vocation for many. This question seeks to determine the candidate’s passion for the field, their goals and what motivates them. What to look for in an answer:

  • Personal connection to sustainability
  • Passion for environmental and social responsibility
  • Clear motivation for their career path

Example:

'After studying textile design at university, I worked my way up in the fast fashion world until I was advising various brands as a freelance marketing consultant. As the climate crisis became more prominent in the media, I grew uncomfortable with the scale of waste in fast fashion, the consumption culture and the unsustainable materials used. I began to educate myself about sustainability in the sector and pivoted to advising slow-fashion brands on how to improve their eco credentials and market their initiatives to environmentally conscious shoppers.'

Can you tell us about your educational background?

This question assesses the candidate's academic foundation. It can also provide clues to their career trajectory so far, along with other areas of expertise that may not be directly related to the job. What to look for in an answer:

Example:

'I have a Bachelor of Arts in Textile Design from Leeds Arts University. After graduating, I moved to Manchester where I completed an internship at Online Fashion Inc., leading to a job as a merchandising assistant. I later moved into the marketing side. After several years in the fast fashion industry, I became curious about sustainability, which led me to pursue various certifications in my free time, including the Business and Climate Change certificate from The Learning Co.'

What environmental legislation and regulations are you familiar with?

By asking this, you can test the candidate’s knowledge and that they can be trusted to advise your company on its regulatory compliance. What to look for in an answer:

  • Familiarity with key national and global regulations and frameworks (e.g. The UK Environment Act 2021, The Paris Agreement)
  • Understanding of which regulations are the most important in your field
  • Confidence in offering advice and communicating information to employees and stakeholders

Example:

'I’m very familiar with the Climate Change Act and the Environment Act. I’ve also studied the Paris Agreement and the EU’s Green Deal in depth. I regularly review updates so that I can accurately advise clients on regulations and recommend changes.'

What appeals to you about working with our company?

The candidate’s answer can tell you how interested they are in working for your company specifically. It also indicates how well they have researched your company when applying. What to look for in an answer:

  • Knowledge of your company’s sustainability practices and/or future goals
  • Passion for the field and your company
  • Indication that they have done their research ahead of the interview

Example:

'I believe that your commitment to sustainable fashion is genuine, and I am impressed by your environmental outreach projects in the local community. Your brand has an excellent reputation, and partnering with sustainability influencers seems to have been a winning marketing strategy. I’d love to be a part of your team and leverage my experience to help you grow and better serve the slow fashion industry.'

What are your strengths as a sustainability consultant?

Asking about a candidate’s strengths or weaknesses is a classic interview question. It prompts them to define themselves and identify what qualities they believe set them apart from others. What to look for in an answer:

  • A balance of hard and soft skills
  • Confidence in their abilities
  • Alignment between their skills and your company’s needs

Example:

'I consider my passion for the environment to be an asset, as it drives me to continue learning and working hard to make a difference. I’m also good at quickly interpreting data and drawing conclusions that I can develop into new strategies or recommendations. Finally, I’m a naturally outgoing person, and I find it easy to communicate with others. This helps me present even complex issues in an accessible way and persuade interested parties to support changes that promote greater sustainability.'

How would you handle conflict with a team member or other interested party?

Sustainability consultants often work directly with other employees and stakeholders and may be entering an environment where these parties are already familiar with one another. This question assesses their people skills and how they deal with communication challenges. What to look for in an answer:

  • Communication skills
  • Ability to listen and understand different perspectives
  • Comfortable with facing challenging situations

Example:

'During a previous project, a team member disagreed with my idea for implementing an upcycling scheme. I remained calm and listened to their concerns. I then went away and conducted a risk assessment for the programme. I presented my findings and asked if we could start with a trial period, limited to our busiest branches. This was a compromise we managed to agree on, and the scheme ended up becoming widely adopted. When conflict arises, I believe in taking a calm approach and ensuring that the other party feels listened to.'

Can you provide an example of a successful sustainability project you worked on in the past?

This question is designed to assess a candidate’s unique skills. It allows you to gauge how valuable they could be to your company. What to look for in an answer:

  • Ability to describe previous success and innovation
  • Results achieved and the impact of their work
  • Relevance to the role/your company

Example:

'At the previous company I consulted for, I implemented a waste-reduction programme. This involved analysing the supply chain to identify inefficiencies. We overhauled the packaging process to focus on minimalism and reusable alternatives. This reduced waste by 40% within a year, and customers who were surveyed indicated their satisfaction with the new packaging.'

How do you approach measuring a company’s environmental impact and developing a sustainability strategy?

Strategic thinking is an important part of a sustainability consultant's job. This question tests the candidate’s technical skills and provides insight into their work process. What to look for in an answer:

  • A meticulous and measured approach
  • Consideration of team members and other interested parties
  • Willingness to embrace technological tools, like software

Example:

'I begin by identifying the most relevant metrics to analyse for the company’s unique goals. For example, this could be their carbon emissions, if their primary goal is to reduce their carbon footprint. I like using tools such as lifecycle assessment software to collect and analyse data. I create a report with my findings, then begin working on ideas for change. It’s important to me to bring all relevant parties on board before designing the strategy. My primary process is to then outline a phased plan for implementation that includes measurable KPIs.'

How do you leverage data in your job?

Data analysis is another key technical skill for a sustainability consultant. This question assesses the candidate’s data skills. What to look for in an answer:

  • Experience with data collection, analysis and reporting
  • Familiarity with sustainability metrics and tools
  • Ability to translate data into actionable insights or recommendations

Example:

'Data collection and analysis are my greatest technical skills. I use tools like MS Excel, along with various modelling software, depending on the area of sustainability that I’m working in – which can vary from one client to another. I believe that data plays a key role in making sustainable changes. I use it to predict potential profits and losses, assess risks and to get a feel for the market. Using data to create detailed reports and presentations can also help build trust with collaborators.'

Do you have any questions for us about the job or our company?

This question can indicate how engaged a candidate is and the degree to which they have considered what it will be like to work for your company. It can also demonstrate their level of assertiveness – an important trait in the sustainability field, where there can often be resistance to change.

What to look for in an answer:

  • Curiosity about the job and company
  • Ability to assert themselves
  • A future-focused approach

Example:

'I’d love to know more about your sustainability goals for the next five years. Since this is a new role, I’m also interested in hearing how you plan to integrate it with your existing departments and what opportunities you foresee for collaboration on future projects, both within the company and with the local community you regularly engage with.'
