How to Start a Career in International Relations and International Business

International relations is one of the most varied and genuinely global career paths available to business graduates. It touches diplomacy, trade, foreign policy, international development, multinational corporations, NGOs, public institutions and beyond. But because the field is so broad, many students find themselves unsure of how to translate their degree into a concrete career direction.

Here is a practical guide to starting a career in international relations and international business.

Understand What International Relations Careers Actually Look Like

The title “international relations professional” covers a wide range of roles depending on the sector and type of organisation. In the private sector, graduates work in global trade, export management, international sales, cross-border project management, government affairs and corporate diplomacy. In the public sector and institutional world, roles include diplomatic services, international organisations such as the United Nations and the European Union, think tanks, foreign policy research and development agencies.

There is also a growing category of roles that sit at the intersection of international relations and technology: digital diplomacy, cybersecurity policy, international data governance and the management of cross-border digital business operations.

Before deciding where to focus your job search, it is worth being specific about which of these directions genuinely interests you. The skills and networks you build differ significantly depending on whether you are aiming for the private sector, the institutional world or the NGO and development space.

Build the Right Academic Foundation

A Master’s in International Relations and International Business gives you a strong theoretical and analytical foundation, but the way you approach your studies matters as much as the qualification itself.

The Master in International Relations and International Business at ESEI is built around project-based learning, meaning students work on real challenges for real organisations rather than purely theoretical coursework. Modules covering diplomacy in the digital age, global governance, international trade and cross-cultural communication equip students with both the conceptual understanding and the practical vocabulary employers look for.

During your programme, take every opportunity to engage with industry professionals, visit relevant institutions and develop opinions about the issues shaping international affairs. ESEI students have had the opportunity to visit institutions such as CIDOB, Barcelona’s leading think tank in global affairs and foreign policy, where they engaged directly with researchers working on contemporary diplomatic challenges, digital transformation in diplomacy and global governance.

Develop Your Language Skills Strategically

In international relations, language skills are not just an advantage. They are often a prerequisite. English is the universal baseline. A second language in Spanish, French, Arabic, Mandarin or Portuguese opens doors in specific regions and organisations.

Be strategic about which languages you prioritise. If you are interested in Latin American trade or Ibero-American diplomacy, Spanish is essential. If EU institutions or African development are your focus, French carries significant weight. If you are drawn to East Asia or the growing influence of Chinese institutions globally, Mandarin is a long-term investment worth making.

Build a Network Before You Need It

International relations is a field where networks matter enormously. The relationships you build during your studies, internships and early career will shape your opportunities for years. This is true in the private sector and even more true in the institutional and diplomatic world, where many opportunities are never publicly advertised.

Attend industry events, follow and engage with professionals in your target field on LinkedIn, reach out to alumni working in roles you aspire to, and use every guest speaker session and field visit during your studies as an opportunity to make a connection.

Get International Experience Early

If you want to work in international relations, demonstrating that you can operate across cultures and languages is more convincing than any amount of theoretical study. An internship in a foreign country, a semester abroad, or even a role that requires regular cross-border collaboration all signal to employers that you are not just talking about international experience but actually have it.

Studying in Barcelona at ESEI puts you ahead of many candidates from the start. Living and working in a city where you navigate a different language, culture and professional environment every day builds the kind of cross-cultural fluency that international employers consistently look for. ESEI’s career services team supports students in finding internship and career opportunities that put those skills to work.

Know Which Organisations to Target

Rather than applying broadly, identify the specific types of organisations where your skills and interests are the strongest fit, and research them thoroughly.

In the institutional world, organisations such as the European Union, the United Nations, the World Trade Organization and the Organisation for Economic Co-operation and Development (OECD) all offer graduate entry programmes, internships and fellowship opportunities. Competition is intense, but strong academic preparation, language skills and demonstrated international experience make a real difference.

In the private sector, multinational corporations, international law firms, trade associations and global consultancies all employ professionals with international relations backgrounds in a wide range of strategic, operational and advisory roles.

Start Building Your Professional Profile Now

Your professional profile in international relations is built over time, but the earlier you start, the better. Read widely about global affairs, develop informed opinions and be able to articulate them clearly. Write about issues you care about, whether through a blog, on LinkedIn or in academic publications. Follow the institutions and organisations you want to work for and engage with their content.

Employers in international relations are looking for people who are genuinely curious about the world, not just qualified to talk about it.
