Deloitte, PwC, EY, KPMG. Names that sound like opportunity, like a first job with real weight, like a r\u00e9sum\u00e9 that opens doors.<\/span><\/p>\n

Have you ever told yourself, \u201cI want to work at a Big 4 firm\u201d?<\/span><\/p>\n

Can you picture starting your career there?<\/b><\/p>\n

But then the doubts show up: what should I study to get there? What if it\u2019s not for me?<\/span><\/p>\n

Among all <\/span>university degrees<\/b>,<\/span><\/a> there isn\u2019t a single one that takes you straight there. These firms hire people from a wide range of backgrounds. What matters most is the foundation you build, your English level, and the experience you bring with you.<\/span><\/p>\n

In this article, we explain what the Big 4 are, which service lines you can join, how a career unfolds from associate to partner, what to study, how to get in, and whether it\u2019s really worth it.<\/span><\/p>\n

 <\/p>\n

What Are the Big 4 Firms and What Do They Do?<\/b><\/h2>\n

The Big 4 are the four largest professional services firms in the world: Deloitte, PwC, EY, and KPMG.<\/span><\/p>\n

They\u2019re often called \u201cconsulting firms,\u201d but their work goes much further: audit, consulting, tax and legal advice, deals, and technology.<\/span><\/p>\n

And they\u2019re a common gateway to a first job. For example, <\/span>KPMG hired 850 professionals in Spain<\/b> between September and October 2025, and 70% of them were recent graduates.<\/span><\/p>\n

The Big 4 Career Path: Levels and Timeline<\/b><\/h2>\n

One of the biggest draws of these firms is that the career path is structured. You move up level by level, and each step brings more responsibility.<\/span><\/p>\n

The titles and timelines below are a typical reference. They vary by firm, country, and service line.<\/span><\/p>\n

How to Get Into a Big 4 Firm<\/b><\/h2>\n

Each firm has its own process, so check the one you\u2019re interested in.<\/span><\/p>\n

Take KPMG as an example. Its process starts with a r\u00e9sum\u00e9 screening, continues with a call and an online test that measures your English level, moves on to team exercises and ends with an interview with the business team.<\/span><\/p>\n

In KPMG\u2019s case, graduate hires tend to start in September and October, although there are selection processes open all year.<\/span><\/p>\n
