The interview process consisted of several stages.

Initially, I was contacted by the hiring manager, who initiated the process by discussing my work experience and motivations for joining ASML. This initial conversation set the tone for subsequent interactions.

Following that, I had an interview with the group leader, where we discussed my past experiences, notable projects, and why I believed I was a suitable candidate for the role. Additionally, a significant portion of this interview focused on technical topics such as C++ concepts (including memory allocation, data structures, and object-oriented programming), Linux proficiency, and design diagrams.

After the initial interview, I progressed to a final round comprising five interviews: two with managers and the remaining with engineers. These interviews followed a similar structure, with approximately 30% of the time spent discussing my past experiences and the remainder dedicated to technical questions. The technical questions in this final round were notably more challenging and required a deeper understanding of concepts than in previous rounds.

Overall, the interview process was thorough and rigorous, encompassing discussions about both my professional background and technical expertise. This comprehensive approach provided a holistic assessment of my suitability for the role at ASML.
