Average Positive Saskatoon, SK

The process took about three months overall, and I remember it feeling pretty smooth for the most part. After an initial recruiter conversation, I went through two phone interviews and then landed on an onsite interview. People were friendly and the vibe didn’t feel hostile, which helped me stay calm and just keep moving through the steps.

Most of the experience was about fit and clarity—HR and the different interviewers seemed to want to understand how I’d think on the job and whether I could work within their environment. When I got to the later stage, the interview didn’t match that earlier energy. The final interviewer didn’t seem to read my resume and didn’t really have a plan for what to talk about, which threw me off in the moment.

Difficult Negative Burlington, MA

My interview loop with Littelfuse felt unusually intense and drawn out. It stretched across four rounds: two phone calls, a video interview, and then an almost six-hour onsite session that required a prepared presentation. Even though several people were pleasant, the overall structure felt discouraging—like the dynamic between interviewer and candidate was tilted in a way that added unnecessary pressure.

The hardest part, honestly, was the presentation-heavy onsite commitment. I also ended up spending time and money to be there, then waited before hearing back. What weighed on me most wasn’t just the workload—it was the mismatch between the effort they asked for and the salary they offered for the experience level and location.
