Perrigo Software Engineer interview questions & guide 2026

The questions listed below are representative of the patterns observed in recent Perrigo interviews. While the specific technical focus may shift depending on the team, the interviewers prioritize understanding your behavioral history, your problem-solving process, and your ability to work within a team-oriented, high-stakes environment.

Behavioral & Leadership

These questions evaluate your soft skills, how you handle conflict, and your ability to work collaboratively in a team.

• Tell me about a time you made a mistake on the job.
• Tell me about a time when you had a disagreement with an internal or external customer; how was it resolved?

Preparation for a Software Engineer role at Perrigo should focus on your ability to articulate your past experiences clearly. You are expected to demonstrate both technical competence and a strong grasp of professional accountability.

Technical & Domain Proficiency – You must be prepared to discuss the technologies listed on your resume in detail. Be ready to explain how your technical decisions have directly impacted quality, safety, or productivity, as these are core values in the healthcare manufacturing space.

Problem-Solving & Adaptability – Interviewers look for how you approach unknown challenges. Use the STAR method (Situation, Task, Action, Result) to structure your answers, specifically highlighting how you navigate situations where you lack complete information or face resistance from stakeholders.

Communication & Influence – As an engineer, your ability to explain complex technical concepts to non-technical partners—such as Quality Assurance or business owners—is critical. Demonstrate your ability to negotiate, resolve conflicts, and maintain professional relationships even when project requirements shift.

The interview process at Perrigo is generally structured to be thorough, involving multiple touchpoints across different levels of the organization. You should anticipate a mix of HR screens, technical discussions with hiring managers, and panel interviews with cross-functional leaders. The pace can vary, but the process is designed to evaluate both your technical fit and your ability to work within a highly collaborative, team-based culture.

The philosophy behind these interviews is to move beyond simple technical validation and truly understand your problem-solving methodology. You will likely face questions that probe how you handle pressure, how you interact with "customers" of your code, and your commitment to continuous improvement. Expect a high degree of professionalism, though be prepared for occasional variations in interviewer preparedness; your goal is to remain focused and drive the conversation toward your core competencies.

This visual timeline illustrates the typical progression from initial screening to deeper technical and behavioral panel interviews. Candidates should use this to gauge their preparation level, ensuring they are ready for increasingly senior-level questions as they move through the stages. Always be prepared for a potential plant tour or site visit, which serves as a final assessment of your comfort in a production-focused environment.

Behavioral Competencies

This area is a major focus for Perrigo. The interviewers want to see how you handle real-world friction. You should be prepared to discuss failures openly and explain what you learned from them. Strong performance here involves demonstrating humility, accountability, and the ability to pivot when a strategy fails.

Be ready to go over:

• Conflict resolution strategies with non-technical stakeholders.
• Examples of taking initiative when no clear path exists.

As a Software Engineer at Perrigo, your primary responsibility is to design, implement, and maintain software solutions that keep the business running efficiently. You will often act as an internal consultant for different departments, translating their operational needs into functional technical requirements. This means you will be expected to collaborate heavily with teams outside of engineering, such as quality, compliance, and plant management.

You will likely be involved in the full development lifecycle, from gathering requirements and prototyping to implementation and ongoing support. Projects may range from automating data collection on the production floor to building out enterprise-level platforms that support product launches. Success in this role is defined by your ability to deliver robust solutions that minimize downtime and increase the overall effectiveness of the teams you support.

A strong candidate for this role possesses a mix of core software engineering fundamentals and a pragmatic mindset suited for industrial application.

• Must-have skills: Proficiency in core programming languages, experience with system architecture, strong analytical problem-solving skills, and the ability to communicate technical concepts to non-technical stakeholders.
• Nice-to-have skills: Previous experience in a regulated industry (such as pharmaceuticals or manufacturing), familiarity with PLC or industrial automation, and experience managing end-to-end platform deployments.
• Soft skills: Demonstrated ability to influence without authority, a collaborative mindset, and high emotional intelligence when dealing with cross-functional disagreements.

Q: How long does the interview process typically take? A: The process can range from a few weeks to several months depending on the specific team and seniority. It is common to have multiple rounds of Webex interviews followed by an on-site visit.

Q: What is the best way to stand out during the interview? A: Demonstrate a deep understanding of the business impact of your work. Candidates who can link their technical decisions to improved quality, efficiency, or safety on the production floor consistently rank higher.

Q: Is there a specific focus on coding challenges? A: While technical competence is expected, the interviews are more heavily weighted toward behavioral and situational questions. Focus on your ability to explain your thought process rather than just providing a textbook answer.

Q: What should I do if the interviewer seems unprepared? A: Take control of the narrative. If the interviewer is not asking specific questions, confidently walk them through your relevant projects, your problem-solving methodology, and why your background makes you a perfect fit for the team's current challenges.

• Structure your answers: Use the STAR method (Situation, Task, Action, Result) for all behavioral questions. This keeps your answers concise and impactful.
• Prepare for the "Why": Always be ready to explain why you chose a specific technology or approach. Interviewers want to see the logic behind your work.
• Research the industry: Have a basic understanding of OTC (Over-the-Counter) product submissions and the regulatory environment of consumer healthcare.
• Engage with the interviewer: Treat the interview as a two-way conversation. Asking insightful, well-researched questions about the team’s current challenges shows you are already thinking like a member of the team.

The Software Engineer role at Perrigo offers a unique opportunity to apply your technical skills in a high-impact, mission-driven environment. By focusing on your ability to communicate complex ideas, navigate cross-functional relationships, and solve problems with both quality and safety in mind, you will be well-positioned to succeed.
