      I interviewed at Siemens (Zug)

      Interview

      I had an excellent experience throughout the Siemens interview process. From the very first interaction, everything was clear, structured, and highly professional. The process was transparent at every stage, with open and straightforward communication. Expectations were clearly set from the beginning, and at no point did I feel left in the dark about the next steps. The interview itself was deeply technical, going beyond standard security questions. It included real-world vulnerability analysis, C code review, and practical problem-solving, which was a refreshing change from companies that focus only on theoretical knowledge. The atmosphere was respectful and friendly, with interviewers who were engaged, supportive, and genuinely interested in my expertise. The discussions felt more like a knowledge-sharing session rather than a rigid evaluation. Even after the final decision, the communication remained professional and respectful, with clear reasoning provided. For those looking for a highly technical security role, Siemens offers one of the best interview experiences. Whether or not an offer is extended, candidates will walk away having learned something valuable. I would strongly recommend applying.
