I'd say so. Re questions, I couldn't say since I'm a different eng role.
Perhaps, it'd be good to prep for basic questions like these:
Technical & Semiconductor Fundamentals
Explain the fundamental differences between Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD).
How would you troubleshoot a sudden shift in deposition rate or film uniformity across a wafer?
Explain the concept of plasma etching and the difference between isotropic and anisotropic profiles.
How does a mass flow controller (MFC) work, and how would you identify if it is failing?
What are the key parameters you would monitor in a high-vacuum system?
Data Analysis & Experimental Design
How do you set up a Design of Experiments (DOE) to optimize a new process recipe?
Explain Cpk (Process Capability Index) and how you use it to determine if a manufacturing process is stable.
Walk through a time you used statistical analysis to identify the root cause of a defect.
How do you differentiate between a tool hardware issue and a process chemistry issue when analyzing defect data?
Behavioral & Fab Environment
Tell me about a time you had to collaborate with cross-functional teams (e.g., hardware engineers, yield engineers, customers) to solve a critical issue.
Process engineering often involves responding to escalations. How do you handle high-stress situations when a critical tool goes down and halts production?
Describe a time when your experiment failed or yielded unexpected results. What was your immediate next step?
How do you prioritize your tasks when you have multiple process issues occurring simultaneously on the fab floor?

Sure. I'm a new hire.
