I applied through university. The process took 2 weeks. I interviewed at KLA (Milpitas, CA) in Jan 2011
Interview
Interviewed by 3 people, two were mechanical engineering managers, the third was the director of engineering for the division. First was done individually then as a panel. Mostly asked questions about the resume and past experience. Did ask some questions about theory. After interview they took me on a tour of the clean room
Interview questions [1]
Question 1
Two cylinders are rolled from the top of a hill at the same time. They are the same mass and diameter. One cylinder is partially hollow in the middle, the other is solid. Which cylinder reaches the bottom first?
I applied online. I interviewed at KLA (Singapore) in June 2026
Interview
Prepare slides on self introduction and previous projects. On site questions about drawings and simulation. Interviewer does not seem to care whether you understand the engineering principles. It was weird that they picked out the pettiest detail in my drawings as if it mattered and told me to revise. I guess KLA is very corporate and that was personal.
When I checked in with the receptionist, she told me that the interviewer I'm meeting with "always use" those rooms. There was a Glassdoor review long time ago on the same position. Something is not right.
It was a very unpleasant experience talking to the interviewer. I could tell that he lied multiple times about his own title, the custom engineering system to host data and so on, and he has a weird attitude. The job post that he wrote was not accurate either.
Interviews in 2026 feel like humiliation rituals; apply to this position at your own risk.
Need to familar with Semi-con fabrication and metrology working priciple knowledge. And it would be better to prepare for the working principle of electron microscope and optical camera. Behavior questions are also asked
I applied online. The process took 3 months. I interviewed at KLA
Interview
4 Technical interviews.
1. Zoom call to understand my previous experience and checking my compatibility to role.
2. Face to Face: Another technical interview for role related tasks
3. CAD proficiency. Supportive and discussion based. Employers are open to learn new ways.
4. GD&T based interview that examines our understanding of sub systems and their functionalities.

Question 1
Apart from the technical side, they asked about the project management skills and my ability to lead my own tasks without supervision.
