Life at HSO




From India to Silicon Valley, and from Malta to Rotterdam: Siddharth and Divya Singh have lived all over the world and worked for the same employers. Together with their daughter, they have seen it all. How did the couple end up at HSO in the Netherlands? In this interview, they share their remarkable story.





For many years, HSO has been recognised for its deep expertise in business applications and its ability to deliver complex, mission-critical solutions for customers across industries. That foundation remains central to who we are. However, the needs of our clients are evolving, as are we.










Expats bring fresh ideas and new energy. But they also face challenges. A new country, a different culture, unfamiliar work habits – and on top of that, building a social life. To exchange experiences and build connections, an expat community was created. Not a formal club, but a space where international colleagues can meet – over lunch, at a drinks event or just for a good conversation. We spoke with three of them about their experience: what was it like arriving in the Netherlands? What stands out in the work culture here? And what does it mean to be part of this community?

"Not your diploma, but your drive. Not your experience, but your curiosity." That seems unthinkable – but not at HSO. "With the right basic attitude, anyone can get started here," says Henk-Jan Brommer, manager of HSO Academy. It sounds ambitious, but practice shows that it works.







Please meet our recruiters in Germany and if there aren't any live vacancies feel free to make contact directly via email with your CV and cover letter.








Professional development begins with collaboration. The biggest steps are taken when we combine our knowledge and talents. Take Albert Hol (Project Manager) and Gerben Mulder (Consultant Management). They worked together on a project for a large retailer, where the billing process was renewed within Dynamics Finance & Operations using Azure Functions. The solution enables the retailer to process and invoice about 150,000 order lines quickly and accurately every day.

HSO has grown rapidly in recent years. This brings change, including in the company culture. To preserve the core of the old culture and embrace new values, a core group has developed a culture compass. Two members of the core group, Behnud and Otto, share their insights.



Find out how we coach and guide a group of leaders to become the next generation of managers. Léonie Havekes and Nathalie Boerefijn share what they’ve learned in their Journey to Lead.



















After graduating as an Industrial Engineer in Turkey, Hatice Aydin decided to pursue a career in IT and Business Applications. She was working on ERP projects and doing a master’s degree in software engineering. "It was at this time I realized I wanted to be involved in international and diverse projects while also gaining experience abroad. And so my path crossed with that of HSO International." Here is the story that brought me to HSO International’s Young Professionals Program (YPP).

You're comfortable building something from the ground up, including your own future team. You bring rigor and precision to compliance work without losing sight of the bigger strategic picture. Why join HSO?
