Zipline Software Engineer interview rejected over manufacturing experience

I started with a recruiter call that was genuinely pleasant. She walked me through the process and answered my questions thoroughly. The next round was with the hiring manager, and I felt that went well too. After that, the timeline became exhausting. I followed up for two weeks and then received a rejection.

They said I lacked experience with manufacturing and maintenance software. What bothered me was that this gap was already visible on my resume, so I felt it should have come up during the initial screening instead of wasting more time. Looking back, the process felt extremely long and draining, and I was left with the impression that it wasn't very efficient or considerate of candidates' schedules.

Location: United States. Overall feedback: Negative. Offer status: No offer.
