ASML builds software that ranges from real-time embedded control code to enterprise applications, and engineers work in scrum teams where new features must fit an existing architecture and stay maintainable. The interview reflected that: it tested how you think about code, not how fast you solve puzzles.
The candidate describes an initial phone screen followed by three rounds: a written assessment, a technical interview and a conversation with the hiring manager. The whole process took about a month, and HR explained each step clearly. The candidate received an offer.
The technical round was the centerpiece, and it centered on code review and design analysis rather than algorithm problems. The candidate was shown code examples and asked to analyze them. Questions covered SOLID principles, garbage collection and reference counting, and how to document and maintain code in a real codebase. The written assessment covered similar ground, including software design and how you would approach a code review.
The candidate felt the interviewers cared more about clear reasoning on design tradeoffs than about perfect answers, and they were comfortable when the candidate worked through something unfamiliar. The manager conversation was mostly culture fit and logistics.
This is a single account, so treat the details as one data point and confirm the steps with your recruiter. For prep, practice reviewing unfamiliar code out loud, explaining why a design is or isn't maintainable, and refreshing how memory management and reference counting work.

Synthesized from candidate reports. Individual experiences may vary.
The candidate reports an initial phone screen before the three formal rounds began. HR then walked the candidate through each following step with clear communication. The account gives few details about the screen itself, so prepare a concise explanation of your background and why you want the role.
The candidate describes an early written assessment that tested conceptual ground such as software design and how to approach code review. It felt more about demonstrating thoughtfulness than speed or memorization. Practice explaining design decisions clearly and in writing.
The candidate was shown code examples and asked to review and analyze them rather than solve algorithm problems from scratch. Questions covered SOLID principles, garbage collection, reference counting, and documenting and maintaining code. The candidate felt that reasoning through tradeoffs mattered more than a perfect answer.
The final round was a conversation with the hiring manager. The candidate described it as mostly culture fit and logistics rather than another technical grilling, with a collaborative tone. Be ready to explain what draws you to the team and how you work with others. The candidate received an offer.
