Full day interview with all candidates and multiple stakeholders all at once. Efficient hiring process, but requires a full day commitment from the candidates to be in Berlin without any compensation.
Easy 30 Minute with construction team. Really chill vibe check. Asked me some random technicals but nothing insane. The technicals were about random class topics such as Thermodynamics and Mechsnics of Materials.
Several technical interview a design interview and a final interview. The process was not pleasant because the interviewers where aggressives and I didn't felt at ease at all. The questions where quite classic advent of code style questions.
