Start your career journey – Aspects of the Programme

Throughout the 8-week Summer Internship programme at EY, you’ll receive a wealth of training in your chosen area to ensure that by the end of the summer, you will have gained skills to last you a lifetime.

However, we also want to provide our interns with an array of opportunities to expand their skillset outside of their day-to-day work and build their network during their time with us. Therefore, we have added lots of opportunities to get involved in throughout the programme.

This includes:

• The EY Sustainability Challenge
• Wellbeing Seminars
• Internship Social Events
• EY Deep Dive Sessions into areas across our firm
• Excel training
• Presentation training
• Interview training
• Professional qualifications training, route presentation and training
• And more…

What to expect

• Day One: After a comprehensive induction, you will begin your journey as an intern within our Climate Change and Sustainability Services (CCaSS) Business. From day one, you will be assigned a buddy on your team who will help you get settled in, and ensure you are set up for a successful summer at EY.
• Your Role: You’ll work as part of team, meet with clients, and make a real contribution to EY projects. We trust the students who join EY for the summer to make a real impact, and we encourage you to do so. You will develop analytical and problem-solving skills, learn how to network, build working relationships and how to lead and manage projects.
• Work/Life Balance: Whilst there will be a certain focus on building your technical skillset, we also want to furnish our interns with the skills needed to manage their workload and create a healthy work/life balance. Throughout this 8-week programme, you will be invited to join us for sessions on a variety of wellbeing topics, as well as plenty of social outings so you can get to know your fellow colleagues and interns on the programme.
• Get to know EY: No matter what programme you choose, we want you to get to know us and what we do. Therefore, you will have the opportunity to attend deep-dive sessions into Assurance, Tax, Strategy & Transactions and Consulting teams and more, so by the end of the summer you will have a great idea of the breath of opportunities at EY. Overall, the EY Summer Internship will offer you the chance to figure out if your chosen career path is the absolute right fit for you.
• Compensation: The EY Summer Internship programme is fully paid - you will work for EY as if you were a full-time employee, therefore, we believe you should be compensated as such.
• Future Opportunities: At the end of your internship if we think you will be a great fit for our team longer term, and you are interested in a career at EY, we may even offer you a graduate position!

In today’s increasingly competitive and accountable business environment, organisations are expected to report on both their financial and non-financial performance. Organisations can no longer afford to ignore sustainability and stakeholder concerns. This shift is driven by a growing emphasis on environment, social and governance (ESG) factors, which can significantly impact a company’s long-term value.

EY’s global Climate Change and Sustainability Services (CCaSS) teams understand the evolving pressures surrounding these challenges. As a result, they can help companies to respond by understanding and evaluating the broader value impacts and outcomes, identifying the opportunities, and supporting the reporting of nonfinancial performance risks to their stakeholders.
