Inside a Big 4 Career: Sean Dyson’s Journey at KPMG

It’s that time of year when graduates and school leavers are starting to apply for their first roles and take the first steps in their careers. With so many different options available, I wanted to explore a few career paths to understand the backgrounds people come from, what the application process is really like, and what advice they can share.

One fantastic route into finance is through an entry-level programme with a Big 4 accountancy firm. But what does that actually look like? What’s the process? Who is it best suited to?

To answer these questions, I spoke with Sean Dyson, a Securitisation Analyst at KPMG UK, who shares his journey and breaks down his experience.

Introduction

I joined KPMG in 2019 on the apprenticeship programme, during my six years at the firm I have gained experience across Audit, Tax, Consulting and Deal Advisory. Alongside my on-the-job experience, I have also studied towards the AAT Level 3 and 4 qualifications and have recently sat my final ACA case study exam.

Your experience applying for the role – how you found the process and any tips for others.

The application process at the time involved an online application, various psychometric tests, an in-person assessment day and an interview. The process can be daunting especially if this is the first time you are applying for a professional role, however there are sample assessments online which you can use to practise, and I would also recommend reviewing the firm’s website to get an understanding of their values and ethos.

Any advice you’d give to someone looking to follow a similar path

I would recommend seeking relevant work experience opportunities. Not only is it something to put on your CV and discuss in an interview, but it also provides insight as to whether a career as an ICAEW Chartered accountant would be a good fit for you.
