Real, anonymous reports from people who interviewed for Software Engineer at Siemens Energy, newest first and distilled into what to expect across the loop.
My process started with a recruiter scheduling the interview, and soon after I sat for a technical screen that felt fairly focused on software fundamentals rather than anything exotic. It ran about half an hour and covered core areas like Python and SQL, plus how to think through data structures. Questions went beyond just naming concepts—I got pushed on async programming, what happens “behind the scenes,” and how the evolution of data structures plays into performance. I also got asked why certain approaches are considered deprecated.
My path began with a group-oriented selection step. I registered and, within a couple of weeks, I was contacted to confirm I’d be participating. After that, the next stage became a group test tied to energy transition themes, and it felt less like a solo technical exam and more like testing how I operated as part of a set.
The initial technical screening focuses on software fundamentals, including Python, SQL, and data structures, with an emphasis on practical application and performance considerations. Candidates should be prepared for questions that explore their understanding of concepts and their implications.
