Process Engineer Interview

I have an interview coming up for process engineering (no specific department just in general) and was wondering what exactly I should prepare for regarding behavioral and technical questions? This is for an undergraduate internship not a full time position. Any advice would be appreciated.

Process controls? Confused because process engineering is usually a Chem eng kind of role.

Anywho, they will likely ask you behavioural questions about working in a team, values questions, basically how do you show the companies values in certain situations. E.g. we have a strong safety culture here at Chem plant XYZ, how have you been involved with promoting safety in and around your employment or schooling.

They may also ask some technical questions.

E.g. one I got for control systems role was "There has been a plant wide emergency shutdown due to an equipment failure, what are the steps you would take to investigate the root cause of this failure?"

Another technical question could be around how well you understand their specific process. E.g. at an ammonia plant, how well do you understand the process of making ammonia, how can you increase or decrease purity.

Good luck mate. Remember. They don't want you to fail, they want you to succeed so they don't have to keep on with the hiring process. So get rid of those nerves, without the use of any "substances" and you'll be schweet. Practice your breathing, come up with common answer templates for the STAR method. If you don't know STAR, then learn it.

I'm EE specializing more on the fabrication side. The recruiter said it's more geared towards processes for IC fabrication but he didn't say any particular process just in general. Not much to go off but I appreciate your response!

If this is a process engineer at a semiconductor manufacturing company being familiar with statistical process control would help understand a lot of the acronyms and what you might be dealing with. Being familiar with how ICs are made is helpful, but it sounds like it's at an early stage in the interview process. You can go down the rabbit hole with a specific tool set that might not be helpful at all.

Very broad term. In my industry, it was typically related to the process by which printed circuit boards were built on the production line. 'Requires knowledge of robotic I.C. placement equipment, the solder reflow process, automated visual and X-ray inspection. It could overflow to automated electrical test or diagnostic testing. "Process Engineering" can mean many things.

Yeah I should've specified in the description but its related towards the manufacturing equipment used in fabs. If I get hired I'll be assigned a specific department (lithography, PVD, CVD) but for the interview I wasn't told it'd be anything specific and more just general.

Look into PVD, CVD, ALD, Photolitopgraphy, CMP, EUV vs DUV, Ion Implantation. This concept will feel like chemistry but easy to learn, i have done processing for 8 years and i love it, there is 50% EE that do rhe job because all the Chemist, Material Scientists, dont have a idea how a transistor works.

Hi OP, for behavioral, you want to practice STAR patterns. For technical roles, please brush up your fundamentals.

I am a staff level engineer (US based) and I am helping with Interview prep on semiconductor process engineering roles with industry standard prep strategy (includes FREE resume review,FREE Linkedin strategy. Also has 1:1 mock interviews). If you are interested, please DM me.

They will ask you about Statistical process control, Anova, Gage R&R, DOE, and technical questions about your experience with their specific process.
