      Senior Data Scientist Interview

      Average interview

      Application

      I interviewed at ControlExpert

      Interview

      Der Bewerbungsprozess war insgesamt gut strukturiert. Die Aufgabenstellung war klar formuliert, allerdings eher auf eine Data-Engineering-Position ausgerichtet als auf eine Rolle im Bereich AI/Data Science. Das erste Gespräch fand als etwa 30-minütiger Video-Call statt. Anschließend gab es einen Online-Probetag, bei dem ich die Möglichkeit hatte, mehr als 15 Kolleginnen und Kollegen kennenzulernen. Der technische Teil des Interviews gehörte zu den besten, die ich bisher erlebt habe. Umso überraschender und auch enttäuschend war es, dass ich am Ende kein Angebot erhalten habe. Es entstand der Eindruck, dass möglicherweise noch keine endgültige Entscheidung zur Einstellung getroffen worden war oder interne (Backoffice-)Entscheidungen eine Rolle gespielt haben. Die Absage selbst wirkte etwas unklar und wenig transparent. Insgesamt war der Prozess an sich positiv, jedoch hinterließ die abschließende Kommunikation einen eher zweifelhaften Eindruck.

      Easy interview

      Application

      I applied online. The process took 2 months. I interviewed at ControlExpert (Düsseldorf) in Jan 2025

      Interview

      I applied online in December.2024 I got interviewed in Jan.2025 The interview took around 40Mins, one interviewer, he asked general questions about my background and the last project I worked on. In Feb, I had a full-online day with the company, they gave me a ML task, it was not difficult. I met the HR and the team, they seemed friendly. In the last round I had a discussion with the a senior data scientist, the communication was not good, He/She did not really stated the question clearly, and did not bother to rephrase. I met another senior person, it was pretty casual meeting, and He/She came late to the meeting. I showed interest in this position, but during the discussion I got the impression that they are arrogant. (No good gut feeling)
