I started with a quick resume-and-experience walkthrough, and the whole feel was pretty relaxed. There weren’t any live coding or algorithm-style technical questions, and instead the discussion leaned heavily on how my past work connected to the role. I remember talking through how I’d used the ASME code on the projects I listed, and the interviewer seemed mainly focused on whether that experience translated to the work they needed.

After that, the next step kept things similarly straightforward. I spoke on a Teams or phone-style screen and then moved into a short interview with a couple of managers. The conversation stayed general and role-oriented—more about my background and what I’d done than anything that felt like a rigorous technical grilling. The format was easy to follow, and I left feeling like it was straightforward to explain my experience clearly.

My process kicked off with a phone screening, then it moved to an online interview on Teams. The whole thing took around three weeks end to end. HR’s responsiveness wasn’t instant, but the communication I did get felt clear enough, and the logistics were simple.

The main interview was fairly direct. I met with the manager and also had HR involved, and the questions were a mix of fit and light technical discussion. They asked how much I knew about the company and then followed up with a handful of technical questions that sounded connected to day-to-day responsibilities rather than abstract theory. I remember feeling like the requirements and expectations had already been explained, which made it easier to stay confident.
