Describe your experience with test automation and ATE. Walk me through a semiconductor fabrication process—what factors can shift outcomes? Explain the end-to-end test flow for a product, from setup to validation criteria. Illustrate how you implemented specific data structures or algorithms (e.g., linked lists, stacks). Discuss a challenging bug or failure mode you identified in test and how you resolved it. Behavioral: “Tell me about a time you disagreed with a manager or teammate—how did you handle it?”
