ASML Software Engineer interview typically runs 4 rounds: phone screen, HireVue video interview, technical interview, and HR/nontechnical interview. It usually takes a few weeks and is fairly straightforward, with a strong focus on your own experience.

We've seen ASML lean hard on resume-specific technical depth rather than abstract whiteboard performance. Multiple candidates reported that once the conversation moved past the initial screen, interviewers quickly anchored on the exact projects, tools, and classes listed on the resume. That means the real test is not whether you can recite generic software concepts, but whether you can explain your own work clearly enough to survive follow-up questions that dig into design choices, tradeoffs, and implementation details.
A recurring theme is that ASML wants software engineers who can operate comfortably around hardware-adjacent problems. One candidate was asked to model an electron detector in a simulation environment, while another faced a question that pulled in cantilever beam stress, which tells us the bar is broader than pure coding. We also see a strong preference for candidates who can connect technical work to the company itself: interviewers asked what candidates knew about ASML and whether they had real hands-on experience. The signal here is practical curiosity plus technical grounding.
The other pattern we've noticed is that ASML seems to value adaptability and communication as much as raw depth. Candidates described the tone as friendly and not adversarial, with questions about teamwork, feedback, and willingness to learn showing up alongside technical prompts. In practice, the people who do best here are the ones who can speak confidently about what they built, why it mattered, and how they would learn the pieces they don't yet know.

Synthesized from candidate reports. Individual experiences may vary.
The process often begins with a short introductory phone call to confirm basic fit, interest in ASML, and whether the candidate has relevant hands-on experience. This stage is light and conversational, with an emphasis on background and motivation rather than deep technical probing.
Some candidates reported a competence test and a cognitive test before the live interviews. These assessments appear to be part of the early screening process and help ASML evaluate problem-solving ability and general aptitude.
Candidates complete a pre-recorded video interview with around 10 questions and unlimited time between prompts to prepare responses. The questions are mostly behavioral and resume-based, covering past projects, university experience, reasons for applying, and what the candidate can contribute.
A single 1-on-1 technical interview follows, often with one technical interviewer and sometimes an HR interviewer present. This round is heavily driven by the resume and past work, with questions that can include C++ fundamentals, implementing a data structure, modeling a system in simulation, and even some non-software technical fundamentals.
