The interview was straightforward. They will ask you what you know about ASML and why you want to work there. Then, they may move into technical questions about kinematics, vibrations, and maybe design. Honestly, the interviewer seemed bored the whole time and ended the call without asking me if I had any questions about the position or company. My advice is to try to go through a recruiter; that way, you can find out the next day if they don't think you're a good fit.

1. You have two cylinders made from the same material. They are made to have the same diameter and length. The only difference is that one is solid and the other one is hollow. Which one has higher stiffness when bending?

2. Again you have two cylinders, but now these two cylinder rods have the same mass and length. Which one has higher stiffness?

3. Taking the two cylinders with the same mass, which one has higher resonance frequency when you impact the end of the rod?
