1. What is a QA Engineer at Burns & McDonnell?

At Burns & McDonnell, the concept of a "QA Engineer" often sits at the intersection of Automation, Controls, and Construction Quality. Unlike pure software companies where QA focuses solely on code, here you are ensuring the integrity of critical infrastructure—ranging from food and beverage processing plants to electrical transmission networks. You are the gatekeeper of quality for engineering designs, control systems (PLCs/HMIs), and on-site installations.

This role is critical because Burns & McDonnell is an Engineering, Procurement, and Construction (EPC) firm. Your work directly impacts the safety, efficiency, and reliability of major industrial facilities. You will likely be involved in the full project lifecycle: reviewing P&IDs (Piping and Instrumentation Diagrams) during the design phase, leading Factory Acceptance Tests (FATs) for control panels, and overseeing commissioning and start-up at client sites.

You are not just testing a product; you are validating a physical system that must operate flawlessly in the real world. Whether you are ensuring a PLC program executes logic correctly or verifying that a construction installation meets safety codes, your role is to deliver projects that meet the high standards of an employee-owned company.

2. Common Interview Questions

3. Getting Ready for Your Interviews

Preparation for Burns & McDonnell requires a shift in mindset. You are not just interviewing for a job; you are interviewing to become an employee-owner. This distinction drives their culture and their evaluation process.

Technical Proficiency & Standards – You must demonstrate a strong grasp of engineering principles relevant to the specific division (e.g., Food & Beverage, Networks, or Transmission). Interviewers will evaluate your familiarity with industry standards (such as NEC, IEEE, or GMP) and your ability to apply them to complex automation and control designs.

Project Execution & Quality Assurance – You will be evaluated on your ability to manage quality throughout a project's life. This includes your approach to verification of design, checking calculations, and managing vendor quality during the procurement phase. You need to show that you can catch errors before they reach the field.

The "Owner's Mindset" – Because Burns & McDonnell is 100% employee-owned, they look for candidates who take extreme ownership of their work. They evaluate whether you treat company resources and client relationships as if they were your own. Passivity is a red flag; proactive problem-solving is a requirement.

Communication & Field Readiness – You will face questions about your ability to interface with diverse teams—from project managers and clients to construction personnel and vendors. Since many roles involve up to 30% travel to job sites, you must demonstrate the adaptability to work effectively in the field during startups and commissioning.

4. Interview Process Overview

The interview process at Burns & McDonnell is thorough and structured to assess both technical capability and cultural alignment. It typically begins with a screening call with a recruiter or HR representative. This conversation focuses on your background, your interest in the EPC industry, and your understanding of the employee-ownership model.

Following the screen, you will likely move to a technical interview with a hiring manager or a senior lead within the Automation & Controls or Quality department. This stage digs into your resume specifics—expect detailed questions about projects you have managed, specific control systems you have programmed (like Rockwell/Allen Bradley), and how you handle quality control in design deliverables.

The final stage is often a comprehensive onsite or virtual panel interview. You will meet with multiple team members, including Department Managers and peer engineers. This round tests your problem-solving skills through scenario-based questions and assesses your "fit" within the team. They will want to see how you handle stress, deadlines, and on-site challenges.

This timeline represents a typical flow, though it can vary slightly depending on the specific global practice you are applying to (e.g., Food & Beverage vs. Transmission & Distribution). Use the time between the screen and the panel to brush up on specific technical standards and prepare your "war stories" of past project challenges.

5. Deep Dive into Evaluation Areas

To succeed, you must be prepared to discuss specific technical and operational areas. Based on the role's demands, focus your preparation on the following domains:

Automation & Controls Logic

For roles involving automation, the core of "Quality Assurance" involves validating software and hardware designs. You need to show you can ensure the "brains" of the facility work correctly.

Be ready to go over:

• PLC & HMI Programming: validating logic for platforms like Rockwell (ControlLogix), Siemens, or Modicon.
• System Integration: How you ensure different subsystems (MES, Batch, Virtualization) communicate error-free.
• Instrumentation: Selecting and verifying protocols for temperature, pressure, flow, and level analyzers.

Example questions or scenarios:

• "Walk me through your process for debugging a complex PLC loop that isn't behaving as expected during a FAT."
• "How do you verify that the I/O list matches the P&IDs before procurement begins?"

Quality Assurance in Design & Procurement

A major part of the role is preventing errors before construction begins. This involves rigorous review processes and vendor management.

Be ready to go over:

• Design Verification: Methods for checking electrical deliverables, panel designs, and cable schedules.
• Vendor Management: How you track vendor progression and conduct Factory Acceptance Tests (FATs) to ensure equipment meets specifications.
• Standards Compliance: Applying ANSI, IEEE, and safety codes to design reviews.

Example questions or scenarios:

• "Describe a time you caught a critical design error during a quality review. What was the impact?"
• "How do you structure a Factory Acceptance Test to ensure a vendor has met all technical requirements?"

Field Commissioning & Safety

The "QA" aspect extends to the physical job site. You must demonstrate that you can translate office design into a safe, working reality.

Be ready to go over:

• Startup Methodologies: Steps for energizing equipment and validating control loops in the field.
• Troubleshooting: resolving installation issues (wiring errors, device calibration) on the fly.
• Safety Culture: Adhering to site safety policies and ensuring designs are safe for operators.

Example questions or scenarios:

• "You arrive on site and find the installation does not match your design drawings. How do you handle this with the construction team?"
• "How do you manage client expectations during a chaotic startup phase?"
