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
