Landing an automation engineer role requires more than just technical ability. You need to demonstrate problem-solving skills, communicate clearly, and show that you understand real-world industrial environments. Here is how to prepare effectively.
Before the Interview
Research the company thoroughly. Understand what they manufacture or process, what PLC platforms they use, and any recent projects or expansions. Mentioning specific details shows genuine interest. In the Gulf that means knowing the difference between interviewing at an operator such as ADNOC, DEWA, or EGA, at an EPC contractor delivering a project for them, and at a system integrator supplying panels and software — the work, the pace, and the expectations differ considerably.
Review the job specification line by line. Map each requirement to an example from your experience. If the role asks for Siemens TIA Portal knowledge, prepare a specific project where you used it.
Brush up on fundamentals. Even experienced engineers get caught out on basic questions. Revise topics like:
- PLC scan cycle operation
- Difference between normally open and normally closed contacts
- Analogue scaling calculations
- PID control theory
- Industrial communication protocols
Common Technical Questions
Expect a mix of theoretical and scenario-based questions:
- How would you troubleshoot a PLC that has gone into fault mode?
- Explain the difference between a function block and a function in Siemens TIA Portal.
- What safety considerations apply when commissioning a new control system?
- How do you handle a situation where a sensor is giving intermittent readings?
- Describe a project where you had to integrate equipment from multiple vendors.
For each question, use the STAR method: describe the Situation, the Task, the Action you took, and the Result you achieved.
Practical Assessments
Many employers include a practical test. You might be asked to:
- Write a short ladder logic program from a specification
- Read and interpret electrical schematics
- Identify faults in a wiring diagram
- Configure basic HMI screens
Practise these tasks in a training environment before the interview. CPD-accredited courses from providers like ED Wartens include practical assessments that mirror real interview scenarios.
Behavioural Questions
Interviewers want to know how you work with others and handle pressure:
- Tell me about a time you had to work under tight commissioning deadlines.
- How do you prioritise when multiple machines are down simultaneously?
- Describe a disagreement with a colleague and how you resolved it.
- How do you approach learning a new PLC platform you have not used before?
Questions to Ask the Interviewer
Asking thoughtful questions signals engagement:
- What does a typical project lifecycle look like here?
- What PLC platforms and software tools does the team use?
- Is there a budget for professional development and training?
- How is the on-call rota structured, and is there site rotation or camp-based work?
- What does the package include beyond basic salary — housing, transport, medical, flights?
- What are the biggest automation challenges the team is facing?
Final Tips
- Arrive early and dress appropriately for the environment — smart business dress is the safe default for office interviews in the UAE, and full PPE will be provided if the interview includes a plant walk-around.
- Bring printed copies of your CV and any relevant certifications.
- If you do not know an answer, say so honestly and explain how you would go about finding the solution.
- Follow up with a brief thank-you email within 24 hours.
Preparation and authenticity win interviews. Combine strong technical knowledge with clear communication and a genuine enthusiasm for automation, and you will be well positioned to succeed.
