Questions and answers
FAQ on training
At us you can currently choose between two vocational training programs: Construction Mechanic:in and Technical Product Designer:in. Both programs typically take 3.5 years to complete and begin in August.
Yes, of course. During an internship you can get to know the profession in a relaxed way. As for the duration, we are flexible. This is the best way to find out if the training suits you.
Very good. We are training because we are looking for long-term reinforcement for our team. If your performance and collaboration are good, we would like to hire you after the training.
As a design mechanic: in our production department, you work practically, getting to know various machines and areas of work and how to independently manufacture things from steel. As a technical product designer: you work predominantly on a computer, creating technical drawings and 3D models for our products, which are then manufactured by our design mechanics.
Usually one day in one week and two days in the other week. The exact times depend on the specific timetable of the vocational school. The vocational school can be in Trier or Wittlich.
Yes, in principle, a shortening is possible. This depends, among other things, on your academic qualifications and your performance during your apprenticeship. If all of this is above average and it makes sense for you, we will discuss the options together.
More than you might think at first glance: Clean air, healthy indoor climate and energy-efficient buildings are central themes of our time. With your work at BLH, you are contributing to solutions that are in daily use by many people.
