Common Automation Technician interview questions
Question 1
Can you explain what PLCs are and how you have used them in your previous roles?
Answer 1
PLCs, or Programmable Logic Controllers, are industrial computers used to control manufacturing processes. In my previous roles, I have programmed, troubleshooted, and maintained PLCs to ensure smooth operation of automated systems. I am familiar with brands like Allen-Bradley and Siemens, and have experience updating ladder logic to optimize production.
Question 2
How do you approach troubleshooting an automated system that has stopped working?
Answer 2
When troubleshooting an automated system, I start by gathering information from operators and reviewing system logs. I then systematically check sensors, wiring, and control devices to isolate the issue. My goal is to identify the root cause quickly and implement a solution to minimize downtime.
Question 3
What safety protocols do you follow when working with automation equipment?
Answer 3
I always follow lockout/tagout procedures before working on any equipment to ensure it is de-energized. I also wear appropriate PPE and adhere to site-specific safety guidelines. Regular safety training and risk assessments are part of my routine to maintain a safe work environment.
Describe the last project you worked on as a Automation Technician, including any obstacles and your contributions to its success.
The last project I worked on involved upgrading an existing packaging line with new PLCs and integrating robotic arms for palletizing. I was responsible for programming the PLCs, configuring the robots, and ensuring seamless communication between all devices. The project required close collaboration with engineers and operators to minimize disruption. After thorough testing and training, the new system improved efficiency and reduced manual labor. The project was completed on time and within budget.

In-depth Automation Technician interview questions
Question 1
Can you walk me through the process of commissioning a new automated system?
Answer 1
Commissioning a new system involves reviewing design specifications, installing hardware, and configuring software. I perform initial tests, calibrate sensors, and verify communication between devices. Finally, I conduct trial runs and make adjustments to ensure the system meets performance requirements.
Question 2
How do you handle situations where production targets are not being met due to automation issues?
Answer 2
I analyze system data to identify bottlenecks or recurring faults. I then collaborate with the production team to implement corrective actions, such as reprogramming or upgrading components. Continuous monitoring helps ensure that targets are met moving forward.
Question 3
Explain how you document changes made to automation systems.
Answer 3
I maintain detailed records of all modifications, including software updates, wiring changes, and hardware replacements. Documentation is stored in a centralized system accessible to the entire maintenance team, ensuring transparency and compliance with industry standards.
