The interviewer is almost as nervous as the candidate in most interviews. There are times when you might question whether you seem sure of yourself, whether you will hire the right person, or whether you are asking the right engineering interview questions. The last question is arguably the most crucial part to worry about when you’re interviewing candidates.
When interviewing people for engineering jobs, the best questions to ask are ones that show they have the skills needed for the job. If you need a problem solver, ask questions about past experiences. If they need to have a specific skill set, ask them directly about their skills.
Six main types of engineering are electrical, mechanical, civil, management, geotechnical, and chemical. Within each of these main types, there are many subfields, such as biomedical or structural engineering.
This article will talk about the best engineering interview questions to ask candidates, with eight different types of questions and advice on how to pick the right ones. It will then give you a list of great questions to choose from. Let’s jump right in.

Branch-Specific Engineering Interview Questions
These questions are critical for finding the right person for the job. They’ll vary greatly depending on your branch of engineering and the position you’re looking to fill. When choosing specific questions, consider the specifics of the job that the candidate will need to know.
Questions to ask:
- Why did you choose to study [engineering branch]?
- Why do you want this position?
- What was your first ever design?
- Have you ever considered working in a different engineering branch?
- When you were working in [branch-specific situation], how did you handle a problem?
Types of Interview Questions for Engineers
There are eight types of questions you can ask candidates in an interview. They each have their own purpose and will reveal something specific about the candidate.
- Behavioral. These questions let you see how the candidate behaved in the past, which lets you guess how they will behave in the future. You can say something like, “Can you tell me how you…” and then ask them how they dealt with something or finished a task.
- Brainteaser. Candidates have to think quickly to answer brain teasers, which are usually math questions. Mental puzzles that are hard to solve can show you who is good at math and who isn’t.
- Case. These questions are about solving problems, so the candidate will have to quickly look at the situation.
- Competency. These questions show what kind of skills the candidate has, such as leadership, communication, confidence, and adaptability, to name a few. You can ask them directly about one of these skills (“How have you shown flexibility at work?”) or ask them something a little less direct (“Tell me about a time you stepped out of your comfort zone”).
- Credential Verification. Credential verification relates to the candidate’s resume. They’re asking about their GPA, past jobs, and other credentials they’ve given.
- Experience Verification. These are like the questions used to check credentials, but instead of asking about jobs and grades, you ask what they did at those jobs or how they got those grades. You could ask, “What did you learn in these classes?” or “What did you do at this job?”
- Nonsense. You might or might not like asking silly questions, but they can show if a candidate is a free thinker who can think about things other than what they practiced before the interview. Every kind of question is fair game, from “What is your favorite animal?” to “What would your superpower be?” They may catch your candidate off guard, but this can show you if they can handle sudden changes.
- Opinion. Opinion questions, like “What is your greatest strength?” and “How would you handle this situation?”, let the candidate show you how they see themselves and why they’re the best person for the job.
