15 Behavioral Interview Questions for Hiring Engineers

When hiring engineers, technical skills are crucial, but assessing behavioral traits is equally important. Behavioral interview questions help identify how a candidate handles challenges, works within teams, and navigates real-world work situations. These questions are designed to gauge problem-solving abilities, communication skills, teamwork, adaptability, and leadership qualities. Below are 15 behavioral interview questions aimed at evaluating these key competencies in engineers.

Behavioral Interview Questions

1. Can you describe a time when you faced a significant challenge in a project? How did you overcome it?

Question Explanation:

This behavioral interview question assesses the candidate’s problem-solving abilities, resilience, and how they approach complex or difficult situations. It highlights how they respond to challenges in a real-world setting, which is critical in engineering, where unforeseen problems frequently arise.

Expected Answer:

An ideal answer will include a specific example where the candidate encountered a substantial challenge—whether technical, time-related, or resource-related. They should describe the context, the specific challenge, and the steps they took to resolve it. For instance, they might describe a technical issue, a client demand that shifted late in the project, or an internal team problem that blocked progress.

The candidate should explain the strategies they used, such as breaking down the problem, brainstorming possible solutions, seeking advice from teammates or mentors, or using technical skills to create a workaround. They should conclude by sharing the outcome and any lessons learned that improved future projects.

Example: “In one project, we discovered that the technology we were using couldn’t support our desired feature set.
