I applied through a recruiter. I interviewed at Siemens
Interview
The interview process was fairly structured and professional. It started with an initial phone screening, followed by a technical interview and then a panel interview with multiple team members. They were punctual, clear about expectations, and asked both behavioral and situational questions. Overall, the experience was smooth and well-organized.

I interviewed at Siemens (Copenhague, Hovedstaden)
Interview
This was a simulated interview for practice, not a real hiring process. It followed a typical structure used by companies in Denmark for data roles: initial screening call, technical test focused on data cleaning and simple modeling, then a technical interview covering Python, SQL and machine learning basics, and finally a short HR discussion. Duration simulated: around two to three weeks. I prepared using public job descriptions and Kaggle datasets.
