3. Getting Ready for Your Interviews

Preparing for a manufacturing and automation-focused quality role requires a strategic blend of technical review and behavioral readiness. Your interviewers will look for candidates who understand both the theoretical principles of engineering and the practical realities of a high-volume, regulated production floor.

Here are the key evaluation criteria you should focus on:

Technical & Automation Proficiency You must demonstrate hands-on expertise with the hardware and software that drive modern manufacturing. Interviewers will evaluate your ability to program and troubleshoot PLCs, HMI/SCADA systems, industrial robotics, and vision systems (such as Cognex or Keyence), as well as your familiarity with object-oriented programming (.NET or C++) and 3D CAD software like SolidWorks.

Quality Systems & Regulatory Compliance Because Ormco produces medical devices, quality is non-negotiable. You will be assessed on your deep understanding of FDA regulations, ISO 13485, and your ability to execute rigorous equipment and process validations (IQ/OQ/PQ) to ensure robust, low-risk machine design.

Problem-Solving & Root Cause Analysis Manufacturing lines experience unexpected downtime and quality deviations. Interviewers want to see your structured approach to troubleshooting. You can demonstrate strength here by walking through past experiences where you identified a root cause, implemented a corrective action, and documented cost savings or uptime improvements.

Cross-Functional Leadership & Collaboration This is a hands-on leadership role. You will be evaluated on your ability to mentor teams of engineers and contractors, collaborate with project managers, and manage outside vendors. Strong candidates will show they can translate complex technical issues into clear, actionable plans for both technical and non-technical stakeholders.

4. Interview Process Overview

The interview process for the QA Engineer and Automation Controls roles at Ormco is thorough and designed to test both your theoretical knowledge and your practical floor experience. You can expect a process that moves deliberately, prioritizing candidates who show a strong alignment with Envista’s continuous improvement and LEAN manufacturing culture.

Typically, the process begins with a recruiter screen focused on your background, salary expectations, and basic qualifications (such as your experience with FDA environments and specific automation tools). This is followed by a technical phone or video screen with a hiring manager. During this stage, expect to discuss your resume in detail, particularly your past projects involving machine design, PLC programming, and process validation. They want to ensure your hands-on experience matches the scale of Ormco's operations.

The final stage is a comprehensive onsite or virtual loop consisting of several cross-functional interviews. You will meet with engineering managers, mechanical designers, and operations leaders. This stage heavily features situational and behavioral questions, technical deep-dives into root cause analysis, and discussions about how you handle vendor relationships and machine downtime. You may also be asked to review a technical drawing or a process flow to demonstrate your analytical skills in real-time.

This timeline illustrates the typical progression from initial screening to the final cross-functional panel. Use this visual to pace your preparation; focus heavily on high-level career narratives early on, and transition into deep technical and regulatory review as you approach the onsite stages.

5. Deep Dive into Evaluation Areas

Automation & Controls Engineering

Your core technical competency is the foundation of this role. Interviewers need to know that you can independently design, program, and maintain the automated systems that build Ormco products.

Be ready to go over:

• PLC and HMI/SCADA Programming – How you architect control software for unique manufacturing projects and ensure robust operator interfaces.
• Industrial Vision and Robotics – Your hands-on experience with systems like Cognex or Keyence, and how you integrate them into a production line for quality inspection.
• System Integration – How you tie together servos, lasers, and custom hardware using object-oriented languages like .NET or C++.
• Advanced concepts (less common) – 3D prototyping integration, non-contact metrology equipment, and custom thermoforming automation.

Example questions or scenarios:

• "Walk me through a time you designed and programmed a control system from scratch. What challenges did you face with the PLC integration?"
• "How do you set up an industrial vision system to inspect products with extremely tight tolerances?"
• "Describe a scenario where a robotic cell was failing intermittently. How did you diagnose and resolve the issue?"

Quality Assurance & Process Validation

In a medical device environment, building the machine is only half the job; validating that it consistently produces quality parts is equally important. You will be evaluated on your adherence to strict quality management systems.

Be ready to go over:

• Equipment Validation (IQ/OQ/PQ) – Your methodology for proving that new or modified equipment meets all internal and external regulatory requirements.
• Regulatory Standards – Your working knowledge of FDA regulations and ISO 13485, and how they impact daily engineering decisions.
• Process Failure Mode Effects Analysis (PFMEA) – How you identify potential risks in a manufacturing process before they result in defective products.

Example questions or scenarios:

• "Explain your approach to executing an IQ/OQ/PQ for a newly installed automated inspection machine."
• "How do you ensure that a change to a machine's programming does not violate FDA or ISO 13485 compliance?"
• "Tell me about a time you used a PFMEA to alter a machine's design during the development phase."

Root Cause Analysis & Continuous Improvement

Ormco highly values LEAN initiatives and continuous improvement. When production lines go down or yield drops, you are the technical responder expected to find a permanent solution.

Be ready to go over:

• Troubleshooting Methodologies – Using structured frameworks (like 5 Whys or Ishikawa diagrams) to trace defects back to their origin.
• Downtime Reduction – Working with maintenance teams to improve machine reliability and redefine preventative maintenance schedules.
• Cost Savings – Documenting how your technical interventions improved productivity, reduced waste, and saved the company money.

Example questions or scenarios:

• "Describe a complex manufacturing defect that was difficult to trace. How did you find the root cause and implement a countermeasure?"
• "How have you previously collaborated with a maintenance department to improve overall equipment effectiveness (OEE)?"
• "Give an example of a LEAN initiative you championed that resulted in documented cost savings."

Project Management & Leadership

As a senior or lead engineer, your ability to guide others is just as scrutinized as your technical skills. You must demonstrate that you can manage projects, timelines, budgets, and people effectively.
