Real, anonymous reports from people who interviewed for Software Engineer at Sandia National Laboratories, newest first and distilled into what to expect across the loop.
My first step was an HR phone call where I walked through the general items on my résumé, and that was followed shortly by a manager call where I went deeper into my technical experience. From there, the process shifted hard into an onsite day that felt designed to evaluate both technical communication and day-to-day collaboration.
My interview started with a simple phone screen that felt more like a conversation than a test. The questions were very straightforward and focused on getting to know me—what I’d worked on, what I was interested in, and how my background fit the role—rather than diving deep into technical specifics. The interviewer was genuinely friendly and open about how the process worked, which made it feel pretty low-pressure.
