Hinterstein brings more than two decades of human resources experience. She began her career at Magyar Telekom, where she worked in various HR roles for over 20 years, including organizational development, HR business partnering, recruitment, employer branding and talent management.
She also served as an HR consultant in Deutsche Telekom’s global HR team. Most recently, she led the HR function at PwC Hungary, where she helped shape the firm’s HR strategy and supported its business units.
A mathematician, economist and certified labor law consultant, Hinterstein earned her HR consulting degree at Erasmus University in Rotterdam. She is also active in academia, teaching at Metropolitan University and Széchenyi István University, and serves as a board member of the Kikapcs Foundation, which supports families raising children with disabilities.
“I believe in the power of positive, collaborative organizations, in data-driven thinking and in innovation, which are fundamental to a consulting company’s operations — and in the idea that HR must act as a strategic partner in supporting business growth,” Hinterstein said of her new role.
“It is inspiring to continue my career in another excellent organization within the industry, where I can apply my knowledge and experience in a different culture. I consider it important to bring new, unique directions to KPMG that shape the community, make everyday life easier and strengthen team spirit,” she added.
With her appointment, KPMG aims to further enhance cohesion within its inclusive and supportive workplace culture, which it describes as open to collaboration, multidisciplinarity and professional development.
As a multidisciplinary advisory firm, KPMG says its goal is to continue adapting to an economy and workplace transformed by technological disruption, helping clients and the wider economy navigate challenges and operate successfully.
