Candidates describe Grainger's software engineering interviews as collaborative and often tied to real work, though the format varies by team and level. A Sr. Software Engineer who received an offer began with a hiring-manager talk, then did a pair-programming session on CodeSandbox in the same languages and frameworks the team uses, followed by a panel of two managers asking behavioral questions, including how they handle conflict at work. They said the coding task closely matched the real job.
An internship candidate who also received an offer reports two back-to-back 30-minute video rounds on the same day with two engineers each. The first mixed behavioral questions, such as handling an upset coworker, with a LeetCode-medium-style problem about sorting character counts in a string. The second was a conceptual system design discussion focused on trade-offs. The candidate described the interviewers as friendly and focused on problem-solving approach and communication.
A Salesforce developer candidate, who did not receive an offer, describes a different shape: a short recruiter screen, a hiring-manager conversation, and a technical session with two developers, with what they understood to be a later behavioral round. The technical task was to write a Lightning Web Component using the wire service and an HTTP callout, with a record update, in Notepad. That candidate felt exact Salesforce recall mattered. These are individual reports, so expect your own loop to depend on the team.
To prepare, practice small tasks in the stack named in the job posting, talk through your reasoning while you code, and have a specific conflict story and a "what I would do differently" project example ready.

Applied online and then waited weeks before getting an email to book the first call, which was a little frustrating because the first available slot was more than a month out. The recruiter screen itself was short and pretty straightforward, only about 15 minutes. After that I had a pleasant conversation with the hiring manager, and that round felt more like a real discussion about my background and the role than a test. The manager seemed genuinely interested in my experience and what I was looking for.
The technical interview was where things got much more specific. I met with two developers, and the questions were centered on Salesforce development rather than broad algorithm work. The main prompt I remember was to write a Lightning Web Component that queried a record through the wire service, showed the data to the user after an HTTP callout, and let the user submit a change back to the record. It was all done in Notepad, which made the syntax part feel more rigid than it needed to be. I also got the sense they wanted exact recall of Salesforce details, not just a reasonable solution using the tools available. After that there wasn’t much discussion, just a quick chance to ask questions before the call ended.
The overall process seemed to be recruiter, hiring manager, technical interview with higher-level engineers, and then a behavioral round with remaining team members. The behavioral question I heard about was along the lines of what I would have done differently on a project if I had known something sooner. Compared with the technical round, that sounded much more conversational and general. I didn’t get an offer, so my main takeaway is to be very comfortable with Salesforce-specific implementation details, especially LWC and wire-service patterns, and to be ready to explain tradeoffs clearly under time pressure.
Prep tip from this candidate
Be ready to write a Lightning Web Component from scratch, including a wire-service data fetch, an HTTP callout flow, and a record update path. Also prepare a concrete example of a project mistake and how you would have handled it differently, since that came up in the behavioral round.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report opening with a short recruiter screen of about 15 minutes or a direct talk with the hiring manager. The Sr. Software Engineer candidate began with the manager, while the Salesforce developer candidate had a recruiter call first. Expect questions about your background and what you want from the role.
The Sr. Software Engineer candidate did a CodeSandbox pair-programming task similar to actual team work in the team's languages and frameworks. The internship candidate reports LeetCode-medium-style coding with engineers, and the Salesforce candidate wrote a Lightning Web Component. Formats may differ by team, so check the posting's stack.
The internship candidate describes a second 30-minute round on conceptual system design, where two engineers wanted to hear architectural decisions and trade-offs. It was reportedly not overly complex. Other candidates did not mention this stage, so it may not appear in every software engineering loop.
The Sr. Software Engineer candidate faced behavioral questions from a panel of two managers, including how you deal with conflict at work. The internship candidate was asked about handling an upset coworker. The Salesforce candidate heard that a later round with team members asked what you would have done differently on a project. Prepare concrete examples with the outcome and what you learned.
Outcomes differ among the reports. The Sr. Software Engineer and internship candidates received offers, with the internship decision arriving days after the final interview, while the Salesforce developer candidate did not receive an offer and described a long wait to schedule the first call.
