Nucor's loop for entry-level mill and maintenance production roles centers on an online pre-hire assessment (basic math, word association, reading comprehension), followed by an on-site interview panel and, for finalists, a third-party TAG (Technical Aptitude Group) exam that candidates learn is typically only extended to the final one or two. Engineering internships lean almost entirely behavioral with a token technical question calibrated to the candidate's class year, and interviewers push hard on teamwork and safety culture (the company uses 'teammate' rather than 'coworker' in questions). The Nucor Technical Academy pathway is a distinct, published funnel that pairs college admission with a plant visit, an interview at the sponsoring mill, and the same pre-hire assessment.

Nucor’s official process
Nucor's public careers site does not describe a general interview process for standard job postings; it points candidates to the jobs.nucor.com portal without laying out steps. The one exception is the Nucor Technical Academy (an electrical-maintenance training pathway with partner colleges), which the company itself lays out as: submit a college application, submit a Technical Academy application, selected applicants schedule a plant visit and an interview with a potential sponsoring mill and take a Nucor pre-hire assessment, offered candidates receive a program position, and on successful completion trainees may still need to interview for a specific entry-level electrical maintenance role. For all other positions the loop must be inferred from candidate accounts.
Initial recruiter call that previewed a 3-4 interview loop, though in practice the candidate reported the number of interviews ended up being smaller than initially advertised.

Final on-site interviewPanel
On-site interview with the hiring manager and other stakeholders. At the end the hiring manager confirmed this was the final interview and began discussing the TAG exam as the remaining step, which the candidate understood as a signal of being a top-one-or-two finalist.

TAG exam (third-party)Online assessment
A third-party Technical Aptitude Group assessment that Nucor typically only extends to the final candidate or final two; delivered by email from an HR generalist after the on-site.
Basic math, word-association, and reading-comprehension sections taken before the interview; a second candidate on the same thread who is four months into the role confirmed this content and said it is a standard entry-production screen.

On-site interviewPanel
Same-day on-site interview with a panel; candidate was asked to wait in the lobby afterward in case the interviewers had follow-up questions, then told to expect an email from HR within about a week. Outcome came the next day as a rejection.
A single interview that leaned heavily behavioral, framed around Nucor's 'teammate' language: scenario prompts about what the candidate would do if they saw a teammate doing something unsafe or off-standard, plus questions about how they operate inside teams in school or extracurriculars. Only two technical questions were included; the technical difficulty is calibrated to the candidate's class year, and as a freshman the candidate got a basic Ohm's Law question (EE major).
Covered · Behavioral, Safety procedures, STAR stories
Interview was 'pretty much entirely behavioral' with no distinct technical section beyond deeper follow-ups about the candidate's stated experience. Recruiter told the candidate they would email in about a week to say whether they had passed the first round, implying a multi-round loop for the engineering-intern funnel even though this specific candidate only completed the first.
