I applied online. The process took 2 weeks. I interviewed at Quantum Machines (Stuttgart) in Feb 2026
Interview
Drei Interviews: 1 Telefon: persönliche motivation, fit fürs team, kleine Python aufgabe
1 persönlich in Stuttgart: Vorstellung, rolle erkärt, Arbeitskultur, als letztes noch eine Signalverarbeitungsaufgabe auf papier zu lösen, am besten in python code.
1 online mit Vorgesetztem: Rolle noch mehr erklärt, persönliches gespräch, selbständiges lösen einer Programieraufgabe. Bei mir ging es hier um einen kompressionsalgorithmus.
Other Validation Engineer interview reviews for Quantum Machines
I had three rounds of interviews. The first was a video interview with the team leader, the second round was also via video with the same team leader and some additional team members and a third interview in person in their office in Stuttgart with a Director. The first interview had a couple of quick coding questions at the end, but nothing too complex. The second was a longer technical interview where I was asked to do some simple signal processing. The third one, in person, was a bit longer with some white board coding as well.
Being my first time doing live coding I was quite nervous but everyone was extremely nice which made things easier.
