13 Behavioral Software Engineer Interview Questions, Answers

Written By John Sonmez

Software Engineering interviews aren't all about coding questions. As has been Simple Programmer's message from the start: Your "Soft Skills" can make or break you in your job hunt and your career success as a whole. 

Learn how to display the exact behavioral attributes companies are looking for — so you can win at your next interview, and go far as a Software Engineer.

How to answer behavioral questions

Be goal-oriented & socially savvy

When the interviewer is asking you to tell them about yourself, it's not to make small talk -- they're judging you for certain attributes they like to see in a candidate.

By telling compelling stories about your experiences, you can let your favorable qualities shine through without being on-the-nose or coming across as dishonest or bragging.

Know what they’re looking for

The main attributes companies are screening for are:

  • Your ability to solve problems while displaying empathy & leadership towards your team members.
  • Your passion for achieving goals in service of the company's mission
  • Your commitment to your technology and using it as well as you can
  • Your personal presentation: How charismatic you are & your communication skills
Prepare your stories in NSAR format

This template for answering behavioral interview questions was created by Gayle McDowell of Cracking the Coding Interview:

  1. Nugget - tease and give a short summary of your story
  2. Situation - explain what happened in a succinct, engaging way
  3. Action - show how you handled the situation, displaying your positive qualities
  4. Result - let them know what happened because of the actions you took or influenced. Back it up with numbers if you can
Make a grid with your practiced stories

To remember the stories you want to use in your answers, it helps to visualize them in a simple grid. Here's an example layout you could choose (again, this is influenced by Gayle McDowell's work):

Most Frequent Software Engineer Behavioral Interview Q's & A's

Let's now get into the questions you'll likely be asked.

You'll find the qualities each question is screening for, how to best approach your answer, and an example answer for all of them.

  • You could give examples of where SWEs go wrong -- and how you'd do it better

Example

"A principle I try to follow as a Software Engineer is to first do a Requirement Analysis for any project, so we've made sure expectations are set before we dive into development."

I appreciated that she took the time to write about her team’s experience and share their solution. It helped me so much!

That’s how I first started getting into open source. I really want to work with more engineers like that—who write about their work and try to help others in the community. So I was excited to see everything your team shares on your blog and on the company’s Github profile."

I've done some research and you seem like a friendly company who're doing great things and working on cool projects. If this job is as advertised, I'm all in on it. This is really what I want to do, and this sounds like it could be the right place for me."

When switching jobs, I always ask myself: How much can I learn and grow from here?

I can't tell you exactly where I'll be in five years, and what position I'll be in. But one thing I know is that if there's a place I can look back from and say: Boy, have I learned a lot and become a better person since then -- then that's where I want to be."

I also talk and share ideas and opinions with fellow Engineer friends. In the past I've been to developer conferences and local events to stay up to date with my knowledge and get new ideas.

Developer books and podcasts do the same: X and Y are some of my favorites. 

I've also set the goal to take at least one new course per year, and I'm working on learning a new programming language right now."

So, I'd be open to hearing why they disagree with my work and their opinion on what could be done to improve it. We're all working for the same organization, and if I have to change something to benefit the team goal, I'm open to doing that if the request is substantiated."
