How Siemens interviews work
Siemens operates in the UK across Siemens Energy, Siemens Healthineers, Siemens Digital Industries, Smart Infrastructure, and Siemens Mobility (trains and rail systems). Each division has its own hiring structure, though all follow Siemens Group principles. For graduate and early careers: online application, online assessments (aptitude and situational judgement), a video interview, and an assessment centre. For experienced hires: recruiter screen, one to two technical or domain interviews, and a competency interview. UK offices include Manchester, Frimley, Congleton, and various operational sites. Note: Siemens divested and restructured several divisions in recent years; verify the specific division you are applying to and its current structure on the Siemens careers site.
Siemens values and what they assess
Siemens's values are Responsible, Excellent, and Innovative. In interviews, Innovative is the most distinctive Siemens value to demonstrate: showing not just that you solve problems, but that you approach them with curiosity and look for better approaches rather than defaulting to conventional methods. "Tell me about a time you came up with a solution that others had not considered" tests this directly. Responsible maps to safety culture (important across all engineering divisions) and sustainability awareness (Siemens has strong targets on sustainability and responsible business).
Siemens in 2026 is focused on digital transformation of industrial processes (industrial IoT, digital twins, automation), sustainable energy (Siemens Energy is a major supplier of offshore wind turbines and grid infrastructure), and healthcare technology (Siemens Healthineers is a world leader in medical imaging). Candidates who understand which Siemens division they are joining and how their role fits the division's strategic direction come across as distinctly better prepared than those who treat Siemens as a generic engineering employer.
Siemens technical and competency questions
For engineering roles: expect technical depth in your domain. Electrical engineers: power systems, control theory, protection relays, grid integration for energy roles; medical device engineering for Healthineers. Mechanical engineers: FEA, fluid dynamics, manufacturing processes, materials selection. Software engineers: embedded systems, SCADA, industrial protocols (Modbus, PROFINET, OPC-UA) for industrial roles; cloud and data engineering for digital transformation roles. Siemens interviewers probe beyond textbook knowledge to how you have applied concepts in practice.
Competency questions in Siemens interviews typically follow a structured format (STAR is commonly used or expected). Prepare specific examples for: a time you solved a complex technical problem, a time you managed a stakeholder conflict, a time you improved a process or standard, and a time you worked under pressure to a critical deadline. For safety-critical roles (rail, energy), demonstrating a genuine commitment to safety culture rather than just compliance awareness is important.
How to prepare for a Siemens interview
Research the specific Siemens division you are joining, not just "Siemens" as a whole. Siemens Energy, Healthineers, Mobility, and Digital Industries are quite different businesses with different markets, technologies, and competitive contexts. Read the division's latest news and any publicly available strategic documents. For technical roles: know Siemens's flagship products in your area (SIMATIC for industrial automation, MAGNETOM for MRI, Velaro for trains) and the technical principles behind them. For sustainability-conscious roles: understand Siemens's DEGREE sustainability framework and its targets. For assessment centres: Siemens group exercises often involve an engineering or commercial scenario requiring structured reasoning and evidence-based recommendation.
