Linkup & Learn May 2021 – Interview with Sonja Wallner




Don't stop, don't quit, even though it is hard.

This is just one of the mottos that has guided Sonja throughout her whole life. For this May's fireside chat, where President Joy Medos interviewed Sonja Wallner about how she became the CFO of one of Austria's most important companies. Sonja gave us insight into her journey to the C-Suite, and discussed topics such as:

  • The importance of recognizing your calling

  • The critical role of managing - and defying - expectations, both one's own and others' (ie - her father expected her to dedicate her life to being a wife and mother)

  • Refusing to stay in a toxic work environment

  • The role of Female Empowerment

Thank you, Sonja for sharing your success story with us and being an inspiration to us all.
