This is what students say about their work at Grenzebach


“ I was impressed by the open and friendly atmosphere right from the start. Immediately, I was involved in projects and was able to put the knowledge I had gained during my studies into practice, for example in the company's own COVID-19 vaccination campaign. My responsibilities and tasks are highly varied and exciting. ”

Laura Krpic

Working Student HR / Business Administration with focus on healthcare

“ Before I started at Grenzebach, I didn't know how complex the field of human resources and, above all, personnel development can be. Grenzebach creates the conditions for a future-proof and demand-oriented development of the employees. Right from the start, I was assigned my own exciting projects, for which I am responsible myself. ”

Jonas Schwertberger

Master Student HR / Learning & Development

“ First a practical semester, then my Bachelor's thesis and ultimately a permanent position - I was really happy to be hired. Even before that, I had only heard good things about Grenzebach. The whole package won me over so that I really wanted to stay. ”
