It was an hour interview with the group engineer manager. He is a Taiwanese staff that was dispatched to the U.S. plant to assist with its construction. He might interview in Mandarine after half of the interview if you can speak that.

Two 1:1 interview with hiring manager and another manager. Pretty straightforward, technical, behavioral and scenario based questions. Both managers seemed nice. They asked about things from your grade to your experience in photolithography and my knowledge of chip fabrication. They want to know if you're willing to work weekends/ late when need arises. Work 9am - 6pm
