Average Neutral Manassas, VA

After the recruiter reached out, I ended up with a pretty light-touch process that still felt structured. I started with a behavioral-focused round, and what surprised me was how little truly deep technical work there was compared to what I expected. A short technical trivia segment showed up during that first conversation, then the next stage went fully technical with a small set of coding-style prompts—leetcode easy in feel—and I was done in about an hour total per interview.

Across the two rounds, I spoke with the same three interviewers. Both sessions were fairly friendly and paced well, and the main theme was understanding me and making sure I could explain what I’d done before. When questions turned technical, they weren’t trying to trick me so much as checking I understood the foundations behind my resume details and could talk through them clearly. There was also some resume deep-diving and a couple of “why this role/company” style prompts in the behavioral parts.

My process started with a phone screening, and then I moved into a one-on-one interview that felt strangely unstructured. The questions I got didn’t line up with the technologies and languages described for the job, and that mismatch threw me off more than the difficulty of the questions themselves.

In the later conversations I had, the format looked more standard but still carried a “prove you really know your stuff” vibe. I ran into a panel-style setup where multiple interviewers probed both behavioral topics and technical areas pulled from what I claimed on my resume—more than I’d seen for a grad-level process. The interviewers were generally friendly and the structure was better there, but it still became clear they wanted specific, concrete familiarity with the applications and languages I listed.
