The overall experience is nice and friendly but in order to pass it, you HAVE to be familiar with Spot Diagrams. Take notes now because they do not use Transverse Ray Plots so it is pretty surprising for students who did not learn spot diagrams in optics.

- Describe the aberration shown in the Spot Diagrams below.
- Analyze the Spot Diagrams and describe what aberration it is.

Applied to KLA Tencor (Singapore). Got shortlisted and the interview was set up pretty quickly, though the whole process took a while because of covid. The three interviewers were really nice and easy to talk to. The interview was about an hour long. It was mostly technical stuff and checking my optics background. They asked a lot of technical questions but were patient. They also really talked about what the job requires and asked if I was planning to study more. There was also a sort of quiz to see how much I actually know about optics. I'm still waiting to hear back, they said it would be within a few weeks.
