I applied through other source. The process took 1 week. I interviewed at Helsing (Berlin) in Feb 2026
Interview
- Leetcode style interview
- sehr ruhiger und professioneller Interview Partner
- Es gab 9 Teilaufgaben, aber ich glaube das kaum jemand alle 9 schaffen wird
- Am Anfang muss man ein CSV file importieren
- Man sollte sich SEHR GENAU die daten anschauen, die man vor sich hat und sich dann für eine Datenstruktur entscheiden, in der man die Daten abspeichert.
Interview questions [1]
Question 1
Die gleiche Frage, wie hier schon mehrfach erwähnt: Eine Material liste importieren und dann bestimmte Metriken berechnen
Had a basic leet style csv handling coding excercise which unlocks stage by stage. Idea was to extract data from csv into the right data structures and process them as per requirements.
Got 24(!) Pages of PDF as prep.
Stage 2 - Leetcode. Was pleasant and OK, the interview is designed that always a next task/challenge part comes after the one you solved.
Depite claiming in their PDF that they will come back within 1 week with feedback, I got ghosted like others among the reviews. bit of a lol
Ghosted.

Question 1
Leetcode - was this topological sorting of aircraft/drone parts that others mentioned. Was not hard, there was also a next question/task after the current one finished
