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 experience dragged on for a couple of months, with a lot of back-and-forth between screenings, panels, and a final onsite-style sequence. I ended up going through roughly five different interviews and countless calls while I waited to hear back. Eventually I did receive an offer, and they put pressure on me to respond quickly.
