  • Recruiter Screen, Then a Data-Pipeline Coding Round and Rapid-Fire LLM QuestionsSiemens · Senior Applied Scientist · Senior+ · Technical Screen · Sep 2026

    I mass-applied online and roughly two weeks later got an email from a recruiter, scheduling a recruiter phone interview. Recruiter phone interview This round mostly asked about my related background (my experience doing LLM post-training), then three behavioral questions (an end-to-end work experience, a time I failed, a time I disagreed with someone). The recruiter said the team works on Physica…

  • Siemens Software Engineer interview: two rounds and a hiring-manager discussionSiemens · Software Engineer · HR Screen · Jul 2026

    In the recruiter call, we agreed on availability and I was told to expect two rounds focused on AI/ML. The HR step was straightforward, with basic questions related to the role. I also sent some details by email and booked a Microsoft Teams slot. A short time later, I met the hiring manager online for the main discussion. We focused on my background and how it connected with the role's needs. The…

    An agency recruiter set up my first interview after an initial chat. It was an online conversation with an engineering manager, and at that point the process seemed to be moving toward something more hands-on. I was told the next stage would have been an onsite, more technical interview, but I never reached it. The manager conversation itself was calm and conversational. I could explain my backgr…

  • Siemens Software Engineer interview: technical depth and resume discussionSiemens · Software Engineer · Technical Screen · Jun 2026

    The Siemens process felt structured and focused on technical depth without becoming a huge drawn-out process. I went through rounds that mixed coding and probing with a manager discussion and an HR step. Throughout, the questions kept coming back to my resume. In the technical rounds, I discussed core data structures and algorithms as well as real-world problem-solving scenarios. I had to explain…
