1. What are some of your greatest strengths?

Employers ask this question to learn more about your personality and how you would fit into their company culture. When answering, it can be beneficial to mention a few of your strongest skills that relate to the job description.

2. What is your experience with developing and testing applications?

This question is an opportunity to show your knowledge of the software development process and how you apply it in your work. You can describe a time when you developed or tested an application, including what tools you used and how you applied them.

Example: “In my last role as a network engineer, I was responsible for testing applications that were being deployed on our company’s private cloud. To test these applications, I would first write unit tests using Python scripts. Then, I would run the unit tests to ensure they passed before running integration tests. After this, I would run the integration tests again to make sure they still passed. Finally, I would deploy the applications.”

3. How do you approach fixing a bug in an application?

This question is an opportunity to show your problem-solving skills and ability to work with a team. When answering this question, it can be helpful to describe the steps you take when working on a bug in an application.

Example: “When I’m fixing a bug in an application, I first make sure that I understand what the bug is and how it’s affecting the system. Then, I try to find out if there are any similar bugs reported by other users. If so, I look at those reports for clues about how to fix the current bug. After identifying the cause of the bug, I write code to fix it and test it thoroughly before deploying it.”

4. Can you tell me about a time when you had to work on a team project that was not going well, how did you handle it?

Example: “I have been using Juniper Networks for many years now, so I know exactly what works well and what doesn’t. One thing I noticed when working with the firewall was that there were some issues with the VPN client. It took me a while to figure out why it wasn’t connecting properly, but once I did, I realized that the problem was due to the fact that the VPN client didn’t support IPv6. If I worked here, I would suggest adding IPv6 support to all of the VPN clients.”

14. Describe a time where you were responsible for completing a task that no one else wanted to do.

This question is a great way to show your willingness to take on challenging tasks and complete them successfully. When answering this question, it can be helpful to mention the specific task you completed and how you felt about doing it.

Example: “When I first started working at my current company, there was an issue with one of our servers that no one else wanted to fix. The problem was causing issues for many employees in the office, so I volunteered to work late to fix the server. After spending several hours troubleshooting the issue, I discovered that someone had accidentally unplugged the server from its power source. Once I fixed the issue, everyone was able to get back to their daily tasks.”

15. When was the last time you learned something new on your own?

This question can help the interviewer get a sense of your ability to learn new things and adapt to change. It’s important to show that you’re willing to continue learning throughout your career, especially if this is your first job out of college.

16. Would you consider yourself a creative person? If so, can you give an example of a time when you used your creativity while solving a problem?

This question is a great way to determine how you approach problem-solving and your ability to think outside the box. When answering this question, it can be helpful to provide an example of a time when you used your creativity to solve a challenge or overcome a hurdle.

Example: “I would definitely consider myself a creative person. In my last role as a network engineer for a small business, I was tasked with creating a new security protocol that would protect the company’s data from hackers. After researching several different methods of protection, I decided to create a system that would encrypt all incoming and outgoing data so only authorized users could access it.”

17. What kind of challenges would you be excited to tackle as a software engineer?

This question is a great way to show the interviewer that you are excited about this role and understand what it will entail. When answering, be sure to highlight your problem-solving skills and ability to work independently.

I have extensive experience in both of these areas, so I know how to troubleshoot problems and implement solutions quickly. In my last position, I was tasked with creating new firewall rules for our company’s servers. I worked closely with my team to create a set of rules that were easy to follow and ensured our data was secure.”

18. What experience do you have with creating test plans?

This question is an opportunity to show your ability to work as part of a team and complete projects. When answering, it can be helpful to mention the specific steps you took when creating test plans in previous roles.

In my previous role as an IT specialist, I used AI to automate many processes within the company’s network.”

20. Do you prefer debugging code or writing code?

Debugging is a crucial part of the networking process, and it’s important that you’re comfortable with this aspect of your job. If you have experience debugging code, explain how you did so in previous roles. If you don’t have any experience debugging code, consider discussing other technical processes you’ve used to troubleshoot issues.

Example: “I prefer writing code because I enjoy problem-solving and figuring out solutions. In my last role, I was tasked with debugging an issue where the company’s network wasn’t functioning properly. After looking at the code, I realized there were some errors in the coding.
