Tips to Get into the Big 4 Firms

Early Internships are Important

If you are a student it is crucial to prioritize securing an internship in the field of Accounting during the summers preceding your sophomore and junior years. This step holds immense significance. While it doesn’t necessarily have to be specifically in accounting, it should encompass areas such as analysis, law, finance, or accounting. The key is to have an internship, even if it is at a lower level. 

By doing so, you will enhance your credentials when applying for the highly sought-after “Junior” internships with the prestigious Big 4 accounting firms, thereby strengthening your arsenal.

To apply for internships, utilize the on-campus recruiting (OCR) system or visit the respective websites of the organizations. Once you secure an internship opportunity, you must truly devote yourself, and ensure that your colleagues recognize you as a valuable addition to their team. By excelling in your internship, you increase your working full-time in any of the big four accounting firms. 

Applying in the Big Four Firms

The first step in planning to apply for work in the big four firms is to learn about the best way to apply in them. Different firms have different application procedures. Some firms require online screening after you have applied for a job and they have shortlisted you. 

Some firms require you to first submit your resume. On the other hand, there are firms that require your resume only during your interviews. So, the point here is to learn the application procedure of the firm that you are applying to. 

The difference when you apply to one of the big four firms rather than any other firms is that there will be 4-6 rounds of interview discussions to decide your position level. The other firms usually only have 2-3 rounds of interviews before they hire you. So you have to be prepared for more tests, and interviews when applying to any of the big four firms. 

Get your Resume Right! 

Regrettably, numerous resumes end up in the rejection pile solely due to formatting errors and spacing mistakes.

The Big Four accounting firms operate in highly professional settings, and they value candidates who can seamlessly integrate into their work culture. A well-formatted resume showcases your understanding of professional norms, such as proper headings, consistent formatting, and the appropriate use of bullet points, thereby signaling your readiness to thrive in a corporate environment.

Learning and Challenges in an Audit Firm: A Professional Training Experience


This document outlines my learning and challenges during my professional training with one of the big four accounting firms. Throughout my tenure, I had the privilege of engaging in various auditing and advisory engagements, which allowed me to develop essential skills and overcome significant challenges. This document aims to provide an overview of my experiences, emphasizing the importance of stakeholder management, time management, confidentiality, and building client relationships.

Integration into a Bigger Team and Engaging with Client Personnel

During the half-yearly and annual audit of a prominent oil refining company, I learned the art of integrating into a larger team and engaging with client personnel at senior levels for data collection purposes. This experience provided insights into the dynamics of working collaboratively with diverse professionals, coordinating efforts, and maintaining effective communication. However, one of the primary challenges faced was forging cordial relationships with senior client representatives while ensuring the extraction of sufficient and appropriate evidence. Convincing busy client representatives to provide necessary data often proved to be a significant challenge.

Time Management

Effective time management is crucial in the audit profession, particularly during peak periods close to deadlines. There were occasions when we had to work late into the night, only to return early the next day to meet project requirements. This demanding schedule required the ability to prioritize tasks, delegate responsibilities, and remain focused under pressure. Balancing multiple engagements and adhering to strict timelines was a constant challenge that required careful planning and organization.


Maintaining confidentiality is a fundamental principle in the audit profession. Throughout my training, I recognized the importance of safeguarding sensitive client information. Handling confidential data, financial records, and strategic plans required strict adherence to professional ethics and standards. Upholding confidentiality was both a responsibility and a challenge, as it demanded a high level of integrity, trustworthiness, and discretion.

Stakeholder Management

The crux of the audit experience lies in managing stakeholder expectations. Whether it was engaging with senior client representatives or working on advisory engagements sponsored by international donors, stakeholder management remained a critical aspect. Understanding the needs and requirements of various stakeholders, aligning expectations, and maintaining open lines of communication were crucial to ensuring successful project outcomes. Building rapport and trust with stakeholders was an ongoing challenge, as different individuals often had diverse perspectives and priorities.


Working on Advisory Engagements Sponsored by International Donors

In addition to auditing engagements, I had the opportunity to work on advisory projects sponsored by international donors. These engagements presented unique challenges, like those encountered in auditing. Time management continued to be a significant concern, given the complexity and diverse nature of the projects. Moreover, stakeholder management remained vital, as collaborating with individuals from different cultural backgrounds required heightened sensitivity and effective communication skills. Balancing the expectations of international donors, local stakeholders, and the organization being advised demanded tact and diplomacy.

My professional training experience with A.F. Ferguson & Co. Chartered Accountants provided valuable insights into the audit profession, presenting opportunities to develop essential skills and overcome challenges. Integrating into a larger team, engaging with client personnel, managing time efficiently, safeguarding the confidentiality, and maintaining stakeholder relationships were key learnings. Overcoming obstacles in data collection, balancing workloads, aligning diverse stakeholder expectations, and upholding confidentiality required adaptability, resilience, and effective communication. These experiences have contributed significantly to my professional growth and prepared me for future challenges in my career.
