Nashua, NHPosted Apr 2025 · Candidate report, summarized by Dataford

I had a fast-paced technical experience that leaned heavily on DSA and lower-level C-style work.

I went in expecting coding, and I ended up with one relatively easy DSA problem, plus additional tasks around C output prediction and debugging. The overall vibe was energetic and moving quickly, like they wanted to see how I handled multiple small correctness checks.

Across the technical rounds, it stayed more about data structures than higher-level design. The interviewers worked in environments where I could actually run and verify code—either over SSH on their Linux setup or via screen share—and they emphasized getting to working solutions. There was a Q&A moment at the end as well.
