My entry point was pretty informal. I met the recruiter at a college career fair, and they were upfront about what the timeline would look like. A few weeks later, I had a short, simple interview where it was mostly a walk-through of my experience and why I wanted the position.

Across the rounds I experienced, the questions stayed light and polite. They focused on strengths and weaknesses, situational awareness, and basic scenarios—nothing that felt like it was trying to trick me. One of the conversations even included straightforward questions about how I felt about working overtime or weekends, which made the expectations feel clear. The total interview time was short enough that it barely felt like a “test.”

After I finally got past scheduling and the paperwork limbo, I ended up doing a phone interview first. It felt like the process had been waiting on other steps, and once I heard back, things moved in a controlled, straightforward way. The first conversation was followed by a technical interview, and what stood out to me most was how long the security side dragged on compared with the actual live interviewing.

The technical round and the recruiter’s structure carried into a later panel interview. That one was pretty formal: I sat in a panel setting with four people plus HR. The overall vibe was organized and professional, not chaotic, and the questions were aimed at both fit and practical understanding of the role. It didn’t feel adversarial, but it did feel like they were systematically checking whether I could operate in their environment. I didn’t receive an offer, but I left feeling like the interview loop itself was predictable—even if the total timeline wasn’t.
