Palo Alto Networks Interview Process

The interview process at Palo Alto Networks can vary in length depending on the position you are applying for, but generally speaking, it is a fairly lengthy process. There are usually multiple rounds of interviews, including both technical and behavioral interviews. The difficulty of the interviews also varies depending on the position, but they are generally not too difficult if you are prepared. Overall, the experience is generally positive, and the company is known for being very thorough in their hiring process.

1. How do you define a good interface?

The interviewer may ask this question to assess your knowledge of the Palo Alto Networks interface and how you use it. To answer, define a good interface as one that is easy to navigate and understand. Explain that you would create an intuitive user experience for customers by designing clear navigation menus and labeling them clearly.

Example: “A good interface should be simple and easy to navigate. I would ensure that all elements are labeled clearly so users can find what they’re looking for quickly. I also believe in creating a user-friendly interface that’s visually appealing and fun to interact with.”

2. What’s your favorite programming language and why?

This question is a great way to see if you’re familiar with the Palo Alto Networks platform. The company uses several programming languages, so it’s important that you can work in them. Your answer should include which language you prefer and why.

Example: “My favorite programming language is Python because of its versatility. I’ve used Python for many projects throughout my career, including automating tasks and creating web applications. Python is also easy to learn, making it an ideal choice for new programmers.”

3. When would you use an array vs linked list?

This question is a technical one that tests your knowledge of data structures. You can answer this question by explaining the differences between array and linked list, then giving an example of when you would use each structure.

Example: “An array is a collection of similar objects stored in contiguous memory locations. It’s faster than a linked list because it doesn’t require traversing to find other elements. Linked lists are slower but more flexible since they allow for insertion or removal of elements anywhere in the chain. I would use an array if I needed fast access to all elements in the collection. For instance, if I was working on a project where I had to sort through large amounts of data quickly, I would use an array. If I needed flexibility, however, I would use a linked list. For example, if I was creating a program that allowed users to add new items at any point in the sequence, I would use a linked list.”

4. Explain how TCP/IP connections work, starting from the ground up.

This question is a basic networking question that the interviewer may ask to test your knowledge of TCP/IP connections. In your answer, you can explain how each part of the connection works and what it does.

Example: “TCP/IP stands for Transmission Control Protocol over Internet Protocol. It’s a set of rules that computers use to communicate with one another on the internet. The four layers are the Network Interface Layer, the Internet Layer, the Transport Layer and the Application Layer. At the Network Interface Layer, the host sends data packets to the network card, which then sends them to the router. The router checks the destination IP address in the packet and forwards it to the correct computer. Then, at the Application Layer, the receiving computer sends an acknowledgement back to the sending computer.”

5. Have you used any of our products before?

This question is a great way to see if the candidate has experience with Palo Alto Networks products. If you have, be sure to mention which ones and what your experience was like.

Example: “I’ve used PAN-OS before at my previous job as a security analyst. I found it very easy to use and navigate through the different features. It also helped me keep track of all the network traffic that was going on in our office.”

6. Describe how DNS works.

The interviewer may ask this question to assess your knowledge of DNS and how it works. To answer, you can describe the basics of DNS and its functions in a simple way that shows you understand how it works.

Example: “DNS stands for Domain Name System. It’s an internet service that translates domain names into IP addresses. For example, when I type ‘’ into my browser, DNS translates this name into an IP address so that my computer knows where to find the website. DNS is also used by other services like email servers.”

7. Are you familiar with any cloud platforms?

The interviewer may ask this question to see if you have experience with the cloud platform that Palo Alto Networks uses. If you are not familiar with their specific platform, consider mentioning a different cloud platform and how it’s similar or different from the one used by Palo Alto Networks.

Example: “I am very familiar with Amazon Web Services because I worked for an organization that used AWS as its primary cloud platform. The two platforms are quite similar in terms of functionality, but there are some key differences. For example, AWS has more features than Palo Alto Networks’ cloud platform, while Palo Alto Networks offers better security.”

8. How would you go about developing a new feature for one of our products?

This question is a great way to assess an applicant’s problem-solving skills and ability to work in a team. When answering this question, it can be helpful to provide specific examples of how you have contributed to the development of new features for previous employers.

Example: “At my current job, I was part of a team that developed a new feature for our company’s firewall product. The process involved several steps, including researching customer feedback, creating a design concept and testing the new feature with beta users before releasing it to the public.”

9. If you were to become part of the Palo Alto Networks team, what can you contribute to improve it?

This question is a great way to assess your knowledge of the company and how you can fit in. When answering this question, it’s important to highlight your skills and abilities that will help Palo Alto Networks succeed.

Example: “I believe my ability to work as part of a team would be an asset to Palo Alto Networks. I have experience working with other cybersecurity professionals and know how to communicate effectively with them. This skill could help me collaborate with others on projects and solve problems together.”

10. Can you tell me about a time where you had to deal with ambiguity?

This question is a great way to assess your problem-solving skills and ability to think critically. When answering this question, it can be helpful to describe the situation in detail and explain how you used critical thinking to solve the issue.

Example: “In my previous role as a network administrator, I had to deal with ambiguity on a regular basis. One time, for example, we were experiencing issues with our firewall that prevented us from accessing certain websites. At first, I thought it was an issue with the firewall itself, but after further investigation, I realized it was actually a DNS server issue. After making this discovery, I was able to resolve the issue.”

11. Tell us about a time when you supported a customer under pressure.

This question can help the interviewer understand how you handle customer service and support. It can also show them your problem-solving skills, communication skills and ability to work under pressure.

Example: “I once had a client who was experiencing issues with their firewall after an update. The issue was causing some of their applications to crash, which caused a lot of downtime for their business. I worked with my team to troubleshoot the issue and found that it was due to a configuration error on our end. We fixed the issue as quickly as possible and communicated with the client throughout the process.”

12. How have you dealt with challenges throughout your career?

This question can help the interviewer get a better sense of your problem-solving skills and how you’ve overcome challenges in the past. Use examples from previous jobs to highlight your ability to work through problems, collaborate with others and find solutions.

Example: “In my last position as a network engineer, I was tasked with creating a new firewall for our company’s servers. The firewall needed to be able to block incoming traffic while allowing outgoing traffic so that employees could access their email accounts and other online resources. After researching different types of firewalls, I decided on implementing an application layer firewall because it would allow us to control what type of data we wanted to allow into the server.”

13. Why Palo Alto Networks?

This question is a great way to show your knowledge of the company and how you can contribute to its success. When answering this question, it’s important to highlight what attracted you to Palo Alto Networks in the first place. You should also explain why you’re excited about working for the organization.

Example: “I chose Palo Alto Networks because I was looking for an opportunity that would allow me to use my skills as a security engineer while also giving me the chance to work with cutting-edge technology. The company has a reputation for being one of the best cybersecurity companies in the world, so I knew I had to apply here. I’m excited to be part of such a successful team.”

14. Do you have experience meeting or exceeding sales quotas?

This question can help the interviewer determine if you have experience with sales quotas and how well you perform under pressure. Use your answer to highlight your ability to meet or exceed goals, as well as your communication skills and problem-solving abilities.

Example: “In my previous role, I had a monthly quota of $10,000 in sales. I exceeded this quota every month for six months straight by consistently meeting with clients and presenting them with solutions that met their needs. This helped me develop my presentation skills and learn more about what organizations look for when hiring cybersecurity professionals.”

15. Tell me about a time when you did not meet a quota, how did you respond?

This question is a great way to determine how you respond to failure. It also helps the interviewer understand your work ethic and commitment to success. When answering this question, it can be helpful to mention that you learned from the experience and used it as motivation to improve.

Example: “In my first year of working at my current company, I was tasked with creating a new marketing campaign for our clientele. I worked hard on the project, but when presenting it to my team, they informed me that it wasn’t what they were looking for. I took their feedback seriously and spent the next week reworking the campaign. The second time around, my team loved it and we implemented it into our marketing plan.”

16. What is your past experience with technical support?

Technical support is an important part of working in cybersecurity. The interviewer may ask this question to learn more about your experience with technical support and how you handled it. If you have past experience, describe a time when you helped someone solve their problem. If you don’t have any previous experience, explain what you would do if faced with a similar situation.

Example: “I’ve never worked as a technical support specialist before, but I did work as a security analyst for a large company that had many different departments. One day, one of the sales representatives called me because they were having trouble connecting to the network. After asking them some questions, I determined that they didn’t know how to use the VPN software properly. I walked them through the process until they could connect.”

17. At Palo Alto Networks we place emphasis on innovation. What are some ways that you’ve been innovative in the workplace?

This question can help the interviewer get a better sense of your problem-solving skills and how you approach new challenges. Use examples from previous work experience to highlight your ability to innovate and come up with creative solutions.

Example: “In my last role, I noticed that our team was spending too much time on manual processes for managing firewall rules. This led me to research automation tools and develop an internal training program for other employees who wanted to learn more about automation. The result was that we were able to reduce the amount of time it took us to manage firewall rules by 50%, which saved us time and money.”

18. The cybersecurity industry is constantly changing, how do you keep up with the latest news?

This question can help the interviewer get an idea of your ability to learn new technologies and adapt to change. Use examples from your current job or a previous one that show you’re willing to take on new challenges and continue learning throughout your career.

Example: “I recently learned how to use Palo Alto Networks’ WildFire, which is a malware detection system. I found it helpful for identifying malicious files in my organization’s network traffic. It was also useful for helping me understand what types of threats are most common among businesses like mine.”

20. Can you describe how you would approach building a product roadmap?

Product roadmaps are a key component of any business, and the interviewer may want to know how you would approach this task. Use examples from your experience that show your ability to plan ahead and create strategies for product development.

Example: “I would first start by researching what’s currently available in the market and identifying areas where there is room for improvement. I would then use these insights to develop a list of features and functions that could be added or improved upon. From here, I would prioritize each feature based on its importance and feasibility. Finally, I would work with my team to determine when we can implement each feature.”
