Real, anonymous reports from people who interviewed for Software Engineer at MKS Instruments, newest first and distilled into what to expect across the loop.
After applying, I got a recruiter call to confirm logistics and go over the role, and it moved pretty quickly and smoothly. I also sent an updated, more tailored resume so the hiring manager could review it. A short time later I interviewed with the hiring manager in a behavioral-style conversation where I walked through my experiences and projects and leaned into my specific strengths. They asked plenty of questions and kept the tone easy and straightforward.
My process started with an HR call that set up my interview with an R&D engineer. The technical part leaned heavily on what I’d built before—my academic work and prior internship projects—and I ended up getting pulled into follow-ups about how those projects worked in practice. The tone was direct, and it wasn’t enough to just describe what I did; I had to explain how it functioned and what happened when things didn’t go perfectly.
