O-I Glass Software Engineer interview questions & guide 2026

The interview process at O-I Glass is designed to gauge both your technical proficiency and your ability to work within a manufacturing-focused, collaborative culture. The following categories represent the patterns identified from previous candidate experiences.

Behavioral and Situational Leadership

These questions assess your soft skills, emotional intelligence, and how you handle the pressures of a complex industrial environment.

• Give an example of a tough situation that you have had to work through before, and what you did to get through it.
• Can you tell us about a time you had to manage conflict on a team?

Preparation for O-I Glass should be balanced between articulating your technical history and demonstrating your "fit" for a collaborative, industrial-focused team. Because the company often values a "family-like" atmosphere, your ability to communicate clearly and build rapport with non-technical stakeholders is just as important as your coding ability.

Role-Related Knowledge – You must be able to connect your technical skills to the specific challenges of manufacturing or large-scale systems. Be prepared to explain how your past work has improved process efficiency, data accuracy, or system reliability.

Problem-Solving Ability – Interviewers are looking for a structured approach to challenges. When answering situational questions, use the STAR method (Situation, Task, Action, Result) to ensure your answers are concise and impact-oriented.

Culture Fit – O-I Glass emphasizes teamwork and cross-departmental collaboration. You should be ready to discuss how you interact with colleagues, how you handle feedback, and how you contribute to a positive team environment.

The interview process at O-I Glass is generally structured to be thorough but personal. Most candidates experience a multi-stage process that begins with an initial screening and progresses toward deeper technical and behavioral assessments. A hallmark of the O-I Glass process is the inclusion of plant-level stakeholders; you may find yourself speaking not just to software managers, but also to plant managers or HR leads from different regions.

The process is designed to be highly informative, often feeling more like a professional conversation than a high-pressure interrogation. Depending on the location, this may involve online video interviews, aptitude testing, or even a site visit to a plant. The goal is to ensure that you are not only capable of doing the job but that you will thrive in the specific operational environment of the facility where you are based.

The visual timeline above illustrates the typical progression from HR screening to final panel interviews. Candidates should interpret these stages as an opportunity to build a narrative: start with your broad experience, narrow down into your technical expertise, and finish by demonstrating how your personal values align with the company’s operational focus.

Communication and Interpersonal Skills

Because Software Engineers at O-I Glass frequently interface with plant managers and non-technical staff, your ability to communicate complex technical concepts in plain language is a key evaluation metric. Strong performance involves demonstrating that you are a listener who seeks to understand the "why" behind an operational request.

Be ready to go over:

• Explaining a technical failure to a non-technical stakeholder.
• How you incorporate feedback from end-users into your development cycle.

As a Software Engineer, your day-to-day work is deeply rooted in supporting the digital backbone of O-I Glass. You will be responsible for designing, developing, and maintaining software solutions that enhance plant productivity. This often means working with internal stakeholders to identify inefficiencies and building custom applications or integrations that bridge the gap between data collection and actionable insights.

Collaboration is central to your responsibilities. You will work alongside quality managers, plant engineers, and IT specialists to ensure that the software you build is not just functional, but also sustainable and scalable for the long term. You may be tasked with managing the lifecycle of specific applications, from gathering requirements and prototyping to deployment and ongoing support, ensuring that the technology keeps pace with the evolving demands of glass manufacturing.

A competitive candidate for this position brings a blend of solid technical skills and a pragmatic, problem-solving mindset. While technical requirements can vary by specific team, the following are generally expected:

• Must-have skills – Proficiency in core programming languages relevant to the role, strong understanding of software development life cycles (SDLC), and experience with database management or system integration.
• Nice-to-have skills – Previous exposure to manufacturing systems, IoT, or industrial automation is a significant differentiator. Experience with cloud platforms or data visualization tools is also highly valued.
• Experience level – Candidates are expected to have a clear track record of delivering software projects from conception to production. Whether you are a mid-level or senior engineer, you should be able to articulate the business value of your past work.

Q: How long does the interview process usually take? A: While it can vary based on the location and specific hiring team, the process typically spans several weeks, involving multiple stages from the initial screen to a final panel interview or site visit.

Q: Is the interview process mostly technical or behavioral? A: It is a hybrid. You should expect a significant focus on your behavioral history and your ability to work within a team, alongside technical discussions that confirm your ability to handle the specific requirements of the role.

Q: What is the best way to stand out during the interview? A: Demonstrate a genuine interest in the manufacturing sector and show that you understand the impact of your code on the "real world." Candidates who ask insightful questions about the plant operations and the company's sustainability goals often leave a strong impression.

Q: Should I expect a coding test? A: Some processes may include technical assessments or aptitude tests, but the focus is often on your past projects and your problem-solving process rather than high-pressure whiteboard coding.

• Research the location: If your interview involves a plant visit, do your research on that specific facility. Understanding the scale of operations in a particular region can help you tailor your answers.
• Prepare for the "Why O-I" question: Have a clear, authentic reason for why you want to work in the glass packaging industry. Aligning your career goals with sustainability or industrial innovation is a strong move.
• Be ready for panel interviews: You may be interviewed by a group of 3–6 people. Practice maintaining eye contact with the person who asked the question while ensuring the rest of the panel feels included in your answer.
• Focus on the "Result" in STAR: When sharing past experiences, don't just talk about the struggle; emphasize the tangible outcome of your efforts, such as increased efficiency or reduced downtime.

The Software Engineer role at O-I Glass offers a unique opportunity to apply your technical skills within a global, essential industry.
