Two men speak in the interview for process engineering job, an interviewer is actually a younger of the two. He is making notes while the job applicant answers his questions.Process engineers can change the world.

And if not the world, they can at least change the entire company and the results of the business, by improving the overall efficiency of the production process.

This amazing job has just one catch–it is not easy to get it in an interview, and you have to prepare for difficult questions.

Ready to learn how to crack this tough nut?

On the following lines we will have a look at some practical, and some behavioral questions you will face in your interview. Let’s start!


A practical interview – one of the toughest out there

I can give you some ideas about this interview, and list questions you may get, but the truth is that in every good company you will deal with several case studies.

You will have to demonstrate your way of thinking and practical skills when it comes to engineering processes. And there is hardly a way to prepare for such technical questions and tests in advance–either you know your job, or you don’t.

But I can give you at least some advice on how to address these questions.

Two managers have a talk in the room, preparing for an interview with an applicant for a process engineer position.When it comes to practical exercises, try to present your opinions in a right way. What does it mean?

You should present your solution to a proposed problem in a way the interviewers can understand.

They should see the benefits of your engineering, benefits for their company–in terms of tangible results your work will bring to the business, or to a particular business process.

Do not try to look like the smartest person in the world. Stay humble, present your suggestions in a clear and simple way, and show some enthusiasm for the challenges that await you in their company.


Personal and behavioral questions – the second part of your interview

Similarly to any other serious interview, you have to count with personal and behavioral questions, simply with a well-designed and sophisticated interview process¬†that tests way more than just your process engineering skills…

What is your attitude to the job? How do you see your role in their company? What is your motivation to work for them? How will you handle various interactions with your colleagues?

All of these things are pretty important for the employer.

Trying to get a better understanding of your goals, motivation, personality, opinions and attitudes, they will ask you many personal and behavioral questions. You will not necessarily get all questions I present below, but you will certainly get some:

  • Can you tell us something more about your education and experience?
  • Tell me something about your latest job, the processes you engineered (or helped to engineer, if you haven’t worked as a process engineer before).
  • Where do you see yourself in five years time? Where do you see your career heading?
  • Why have you decided for career in process engineering?
  • What do you want to accomplish on this position in our company?
  • What are your strengths and weaknesses?
  • Why should we hire you and not somebody else for this particular position?
  • Describe me a situation when you felt hopeless in your job, and didn’t know how to progress.
  • Describe me your most successful engineering experience, and tell us who helped you with your success.
  • Describe the biggest failure of your professional career.
  • Describe a situation when you reached a goal and tell us how you achieved it.
  • Describe a problem you were unable to solve.
  • Describe a situation when you were under pressure in work. How did you handle the pressure?
  • Tell me about a time when you showed drive in work.
  • Tell us about a conflict you had with one of your colleagues, and how you eventually managed to solve the conflict.


Special tip: If you find these questions difficult, or experience anxiety, or feel overwhelmed with information, have a look at our Interview Success Package. Great answers to all difficult personal and behavioral interview questions will make your life much easier on a big day….


An HR manager is lost in thought as she observes the job applicant, and their effort with behavioral questionsStay human, and honest

The most important thing is to stay honest, and human. To say that you always solved every problem, or never felt stress in your job, would not lead to a success in an interview.

The interviewers want to hear that you can admit making a mistake, and learning from the mistake, and that you can co-exist with your colleagues at work--though you may struggle with relationship sometimes–just like everyone else does…


Technical questions other than case studies

Once the behavioral interview ends, and once you have dealt with the case studies (or even before dealing with them), the interviewers can ask you a few simple, straightforward technical questions.

Your answers to these questions help them to get a basic grasp of your technical skills, and theoretical knowledge of process engineering.

Bear in mind though that this part of an interview will not necessarily come. To the questions:

  • What do we mean by a prototype?
  • What is cascade loop and how it works?
  • What can cause a damage to a hydraulic pump?
  • … (the questions will depends on the particular job you apply for–the processes you will engineer, the particular industry you’ll work with ,etc.)

Special Tip no.2: You can download a full list of questions (without answers) in a one-page long .PDF document, and practice your interview answers anytime later:

Conclusion & Next Steps

Things went well in the interview, and people are shaking hands.To succeed in an interview for a process engineer position is not easy. While you won’t compete with many other people for the job (typically less than five candidates in total), you will face a difficult interview.

Personal, behavioral and technical questions, and the ever-threatening practical case studies….

Honestly, it is not easy to prepare for the technical case studies in advance, becasue you can not really tell the exact questions you will get. Either you know your job and are ready for the technical questions, or you won’t make it.

On the other hand, you can prepare for the personal and behavioral questions–the second part of the interview, equally important as the technical part. Check our Interview Success Package to learn how to answer all difficult questions.
