I applied online. The process took 4 weeks. I interviewed at Siemens (Princeton, NJ) in Mar 2016
Interview
Phone screening then challenge then that's it!! It wasn't bad at all. the people on the phone asked many weird questions baout background and what I did. Then they asked me to rate myself between 1 and 10. Being confident I answered 9. then they thought that reflects a bad image of my personality. Weirdos!!

I interviewed at Siemens (Copenhagen, Capital Region)
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.

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.
