The interview process involved questions based on my resume, a task related to image processing, a guesstimate question, and some HR questions. I'm not sure what they were looking for, and they seemed to dislike it when I showed technical expertise.

The interview was pretty straightforward. They went into what the job actually entails and asked what I would do if I got the position. The manager asked about my past work history and what I thought about the latest semiconductor trends. They also asked if I knew any scripting languages and if I had experience working in a clean room. Since it was an entry-level role, I didn't overthink it.
