Katja Bernhardt

student intern
My name is Katja, I am 21 years old and from Germany. At this moment I am studying German law at the University of Hamburg in the third semester. Through the university, I am absolving one of my internships at the law firm Heffels- Spiegeler in The Hague.
Since my time in Canada and the United States after high school it was clear to me, that I wanted to collect more experience abroad. After extensive research I found this law firm which persuaded me immediately with its field of law and its friendly people working there. Especially the international work represents my interest in culture and languages.
Furthermore I caught a lot of interest during my study in civil law, especially business law, in which Heffels-Spiegeler puts its emphasis on.
My goals for this internship are to collect as much experience as possible that can improve both me as a person and  my legal knowledge, deepen my understanding towards business law and therefore eventually find a suitable field for my future career.
