A Schnuppertag lets both sides test fit. Arrive on time in the clothing the company suggested, bring a notepad, and expect simple tasks rather than a showpiece project.
Listen to safety briefings carefully. Asking one precise question about a machine or process often reads better than a long speech about your ambitions. Supervisors notice whether you follow instructions the second time as carefully as the first.
After the day, send a short thank-you note that mentions one concrete task you tried. Avoid generic praise. If the trade felt wrong, that is useful information — better discovered on a Tuesday trial than six months into a contract.
If you need support preparing questions or reading the company’s expectations, our employer introduction guidance covers how Schnuppertage usually unfold in craft and industrial settings.
