Candidates who interviewed for software-related roles at 3M describe conversations that lean on concrete examples of past work more than on algorithm drills. These roles had different titles (a DevOps engineer, a junior developer and a technical specialist), so treat each account as a separate data point. All three reported no offer.
One candidate began with a casual phone screen with the hiring manager. A video round with the engineering manager followed, then an onsite with the manager and facility management staff. That candidate said the interviewers wanted proof of delivered impact, not general talk about strengths.
Another candidate, a junior applicant, was asked to walk through prior roles and the data analysis tools they had used. They were also asked to describe a hard problem they solved step by step, and how they handle tight deadlines. Motivation questions covered why 3M and where they saw themselves in five years.
The third candidate, a technical specialist, had a recruiter phone screen and then a Teams call with a hiring manager and a senior colleague. Questions mixed customer-facing situations, designing test cases for a scenario, and Java features. That candidate also mentioned presentations at on-site rounds and about two months of elapsed time with slow communication late in the process.
A sensible preparation plan is to prepare a few project stories with context, actions and measurable results. Review the fundamentals of the language named in your job posting, and practice reasoning aloud through test cases. The evidence is limited to three accounts, so confirm the exact format with your recruiter.

Synthesized from candidate reports. Individual experiences may vary.
Two candidates report starting with a phone conversation, either with a recruiter or directly with the hiring manager. One described it as casual and tied to the actual job, covering their background, previous roles and what they had worked on.
Two candidates describe a video round with a hiring or engineering manager, once alongside a senior colleague. Conversations covered the role, past projects and how the candidate solves problems, and were described as friendly but pointed.
Candidates report questions on difficult situations, tight deadlines, tools used and motivation for joining 3M. One was asked to think through test cases for a scenario and answer Java feature questions. The technical portion may be light on algorithms, based on one report.
Two candidates mention later-stage rounds. One had an in-person interview with the manager and facility management team. Another described on-site rounds that could involve presentations. Both ended without an offer, and one reported long gaps and silence after final rounds.
