• How do you structure data analysis or reporting using tools like Excel or custom scripts?
• How do you approach troubleshooting a system when you do not have immediate access to complete documentation?
• Walk me through how you review technical specifications, single-line diagrams, or system architectures.
• What approaches do you use to test and validate process software before deploying it into a live environment?

Collaboration & Project Management

These questions assess how you prioritize work, coordinate with cross-functional teams, and communicate technical details to non-technical stakeholders.

• How do you handle competing priorities when multiple plant managers or stakeholders request urgent fixes?
• Describe a time you led a initiative or project from initial requirement gathering to delivery.
• How do you explain complex technical concepts or system changes to operational workers on the mill floor?

Preparing for an interview at WestRock requires a balanced focus on behavioral performance, communication, and practical technical competence. Interviewers value authenticity, clear communication, and alignment with corporate core values over theoretical algorithm puzzles.

Role-Related & Domain Knowledge – You must demonstrate a functional understanding of software integration within industrial or enterprise environments. Focus on showing how your technical skills solve business problems rather than focusing purely on abstract code optimization.

Problem-Solving & Self-Direction – WestRock values engineers who take initiative in complex environments without requiring hand-holding. Show that you can evaluate an ambiguous problem, break it down logically, and execute an effective fix independently.

Behavioral & STAR Structure – Most structured questions rely heavily on the STAR approach. Clearly outline the Situation and Task, detail your personal Actions, and end with quantifiable Results or key learnings.

Culture & Manufacturing Fit – WestRock strongly emphasizes character, safety, and respect for plant operations. Demonstrating humility, strong work ethic, and enthusiasm for supporting physical manufacturing facilities creates a strong positive impression.

The hiring experience at WestRock is straightforward, relational, and structured around assessing candidate character, practical skills, and organizational fit. Depending on whether you connect through campus recruiting, career fairs, or online applications, the process moves efficiently through clear stages.

Initial interactions frequently begin with a recruiter or hiring manager conversation. This initial touchpoint focuses on reviewing your resume, setting expectations regarding work environments (such as plant or mill site interactions), and discussing your career interests. Following the screen, candidates typically participate in a panel interview—either virtually or onsite—where you will meet with cross-functional team leads, engineering managers, and HR partners.

Onsite interviews often include a facility or mill tour, offering candidates direct insight into the manufacturing operations. The atmosphere across panel discussions is conversational rather than aggressive, focusing heavily on situational behavior, teamwork dynamics, and practical engineering judgment.

The timeline above details the progression from initial application to final selection. Candidates should use this schedule to structure their preparation, focusing early effort on STAR behavioral stories and converting that momentum into confidence during panel discussions and plant visits.

Behavioral & STAR Proficiency

Behavioral alignment is the single most heavily weighted aspect of the WestRock evaluation process. Interviewers assess your work ethic, integrity, safety consciousness, and how well you integrate into collaborative team settings.

Be ready to go over:

• Conflict Resolution – Practical strategies for handling peer disagreement, task handoffs, or missed deadlines.
• Accountability – Demonstrating personal responsibility when a system change or project delivery experiences issues.

As a Software Engineer at WestRock, your primary focus centers on delivering software solutions that support operational efficiency, enterprise infrastructure, and digital plant initiatives.

You will spend a significant portion of your time designing, developing, and maintaining software modules used by operational teams, plant managers, and corporate support functions. This involves writing clear code, building internal APIs, maintaining database integrations, and configuring monitoring dashboards.

Collaboration is central to the role. You will work side-by-side with cross-functional engineering teams—including process, electrical, and maintenance engineers—to capture business requirements and translate them into software tools.

Additionally, software engineers contribute to continuous improvement efforts across technical workflows. You will help troubleshoot legacy software systems, update system documentation, automate manual data entry tasks, and participate in project planning reviews to ensure solutions scale across multiple facilities.

Successful candidates bring a solid foundation in computer science or engineering fundamentals, coupled with a practical, pragmatic approach to software development.

Technical & Professional Qualifications

• Must-have skills – Strong proficiency in at least one modern programming language (such as Java, C#, C++, or Python), solid SQL database skills, and clear logical problem-solving abilities.
• Must-have experience – Proven experience building, testing, and supporting software applications or system tools; familiarity with standard version control systems (Git).
• Nice-to-have skills – Experience with industrial automation standards, process control systems, manufacturing execution systems (MES), or modern cloud infrastructure platforms (AWS/Azure).
• Nice-to-have experience – Prior exposure to manufacturing, paper/packaging mills, distribution logistics, or enterprise hardware-software integrations.

Interpersonal & Soft Skills

• Clear verbal and written communication skills to articulate technical ideas to non-technical operational teams.
• High degree of personal accountability, adaptability, and self-motivation.
• Respect for workplace safety procedures and team-oriented collaboration.
