Is it also possible to send an unsolicited application?
Yes, if you cannot currently find a suitable position, we would still be happy to receive your unsolicited application. Simply describe the area in which you see yourself and what motivates you - we will then check internally for suitable employment opportunities.
How does the meeting or interview process work?
Depending on the position and location, we conduct initial interviews by phone or video. In the next step, we will invite you - if possible - to a personal interview on site. This is not just about your qualifications, but also about whether we are a good match.

How flexible are working hours and locations at Megger?
Flexibility is important to us. Depending on the position, we offer flexible working time models and mobile working. In some areas, such as production or on-site service, fixed working hours naturally apply - but here too with predictability and consideration for your life.
What does the induction at Megger look like?
You will receive structured support right from the start - with an induction plan, fixed contact persons and colleagues who will support you. The aim is for you to quickly feel comfortable and be able to work independently.
