      Average interview

      Application

      I applied through other source. The process took 3 weeks. I interviewed at OPTIML (Zürich) in Sept 2025

      Interview

      Der Bewerbungsprozess bestand aus mehreren virtuellen Gesprächen, darunter zwei technische Interviews und ein Gespräch zum kulturellen Fit. Der Ablauf erstreckte sich über mehrere Wochen. Das Feedback erfolgte nach einiger Zeit. Die technische Aufgabe war anspruchsvoll, stand jedoch nur teilweise im Zusammenhang mit der ausgeschriebenen Position. Der gesamte Austausch verlief professionell und respektvoll.

      Question 1

      Wie würdest du eine angepasste Version von JSON.stringify implementieren, die bestimmte private Felder eines Objekts ignoriert und den Rest serialisiert, um HTTP-Requests anhand des Request-Bodys zu cachen?
