Common Principal Engineer Interview Questions

What led you to pursue a career in engineering?

There are many reasons why someone might pursue a career in engineering. Some people are drawn to the challenge of designing and building complex systems. Others are interested in the opportunity to use their technical skills to solve real-world problems.

The interviewer is likely asking this question to get a sense of the candidate's motivations for pursuing a career in engineering. It is important to understand the candidate's motivations because they will play a role in determining whether or not they will be successful in the role.

For example, candidates who are driven by the challenge of building complex systems may be more likely to thrive in an engineering role that requires them to do just that.
