Career

Group Internal Audit at ISS

Tell your story… Kalli Tzioti.

From Group Internal Auditor to Global Commercial and Finance Manager.
I would have never thought of my career at ISS to progress so rapidly.

I began my ISS career as Group Internal Auditor. Only 10 months later, I became a Contract Auditor which gave me stronger operational insights. 10 months later again, I became Global Commercial and Finance Manager. This is definitely the position I saw as the next step in my career.

How and why did you become a Group Internal Auditor at ISS?

I was headhunted for the position. When I was approached, I looked closer at ISS’ profile. The international nature of the position, the opportunities to get exposed very quickly to complex elements, and having individual responsibility for projects while working in a very close team, convinced me to take the interview.

Before becoming Group Internal Auditor at ISS, I worked as external auditor at E&Y in Athens where I audited big international clients and completed my professional certification as ACCA. 

How did you experience the role as a Group Internal Auditor at ISS?

The role as Group Internal Auditor is far from what most people think. We are not rigid numbers people ticking boxes. A Group Internal Auditor at ISS travels to different countries to conduct interviews and test the controls and processes in order to understand how ISS complies with laws, accounting standards, contractual requirements, and ISS policies.

All this takes a lot of preparation because you always have to be up-to-date with everything that happens in the HQ, the countries, and the external environment. You have to be able to take responsibility for your actions, your recommendations, and your work, as you will find yourself in situations where people try to push back your findings.

Therefore, you sometimes have to take the role of a psychologist: You will audit and interact with different people and you will need to make them understand that they will benefit from the auditing process.

I have really enjoyed being a Group Internal Auditor as the constant travelling has exposed me to different cultures and places and the work with all hierarchies in the management has greatly improved my communication and presentation skills.

What do you consider your biggest achievement and what brings the future?

One of my biggest achievements is the trust of my colleagues and the fact that they will consider me a reliable person to solve a problem. I am also very happy about the fact that I got offered several internal job opportunities while working at Group Internal Audit because people valued the work I have done. I firmly believe that if you work hard you have many opportunities to explore various roles at ISS and to shape your career the way you want. I am currently in the first months of my new position and very happy about it but I am already looking forward to my future challenges! I feel that it is a great privilege to see the potential for long term career progression in the same company.

How has your career been developing then?

I started as Group Internal Auditor doing baseline audits and key account audits. Quickly hereafter, I got the opportunity to work with special priority audits where I reported to the Group’s top management. Ten months later, I took over the position as interim CFO for ISS Czech Republic and Slovakia for 6 months which led me to become Regional CFO for Eastern Europe. Within this position, I still have a lot to learn and I am looking forward to get a good understanding of the requirements to develop and perform in my new role.

Tell your story… Shane Horan.

From Group Internal Auditor to Regional Chief Financial Officer.
I would never have expected that just after a year I would advance to a role as a Regional CFO and work so closely with the Group’s CEO, Jeff Gravenhorst, and CFO, Pierre‐François Riolacci. You could say that my story within ISS started as a personal love story and led to a professional success story.  

How is a love story related to your professional success story at ISS?

After my graduation in Accounting from the National College of Ireland, I started working as an Audit Senior in the banking segment at E&Y while doing my ACA certification. Three years later, I relocated with E&Y to Bermuda where I fell in love with a Danish woman. After a stopover as a Group Accountant and an Internal Auditor in Berlin, we decided to settle down in her home country -  Denmark. It wasn’t long before I got in touch with ISS.

From the very beginning I found the diverse line of work within the role as Group Internal Auditor very interesting. Besides auditing financial processes, Group Internal Audit at ISS are also involved in operational audits (fx. Health and safety) across the world. 

How does the role as Group Internal Auditor at ISS differ from your previous positions?

The biggest change for me was to move from financial audits to operation-focused audits, giving you deep insights into different operational areas in different countries. The change was challenging but the team has great training systems in place to teach you how base line audits and key account audits work.

As the role requires you to talk with leadership teams and CFOs you must be motivated and a good communicator.  Even top management and the Group CFO may be involved in your audit, which for me was a huge surprise.
