1. What do you know about Cloudflare’s products?

This question is a great way to test your knowledge of Cloudflare’s products and services. You can use this opportunity to show the interviewer that you have experience with their products, how they work and what benefits they offer.

Example: “I’ve used Cloudflare for several websites I’ve worked on in the past. One of my favorite features is the free SSL certificate because it makes it easy to protect customer data online. Another feature I like is the firewall, which helps me block malicious bots from accessing my website.”

2. Tell me about a time when you had to deal with an angry customer, how did you handle it?

An interviewer may ask this question to assess your customer service skills. They want to know how you would handle a challenging situation and if you have the ability to diffuse it. In your answer, try to show that you can remain calm under pressure and use your problem-solving skills to find solutions for customers.

Example: “I once had a client who was upset because their website wasn’t loading properly. I asked them what they were experiencing on the site and they told me that it took too long to load. I explained to them that Cloudflare is designed to speed up websites but sometimes there are issues with certain sites. We worked together to troubleshoot the issue until we found a solution.”

3. How would you describe your sales style?

Salespeople are often required to sell their products and services to clients. Cloudflare is a company that sells its services, so it’s important for the interviewer to know how you would approach selling your product or service to customers.

Example: “I believe in being honest with my clients about what I can offer them. If I don’t think they’re ready for our more advanced services, I’ll tell them that we have other options available. However, if I feel like they’re ready for something more complex, I will explain all of the benefits of upgrading to a higher-level plan.”

4. Why is DNS important for an organization?

DNS is a service that translates domain names into IP addresses. It’s an important part of the internet, and your answer should show you understand how it works. You can also mention some of its benefits to the organization.

Example: “DNS is essential for any company because it allows users to access websites by using domain names instead of IP addresses. This makes it easier for people to remember website URLs. DNS also has many other advantages, including improved security, faster page loading times and lower costs.”

5. Do you have any experience with Linux?

Linux is a type of operating system that Cloudflare uses. If you have experience with Linux, explain how it has helped you in your previous roles.

Example: “I’ve worked with Linux for the past five years and I find it to be an efficient way to manage servers. In my last role as a web developer, I used Linux to set up new websites on Cloudflare’s platform. This allowed me to streamline the process of setting up new sites and improve the overall efficiency of our team.”

6. Are you able to work in a fast paced environment?

Cloudflare is a company that requires its employees to work in a fast-paced environment. The interviewer may ask this question to determine if you are able to adapt to their working style and pace. In your answer, try to explain how you can handle working in a high-pressure situation.

Example: “I am very comfortable working in a fast-paced environment. I enjoy being challenged by new projects and having to meet tight deadlines. Throughout my career, I have worked for companies where the workload was always changing. This has helped me become more flexible when it comes to adapting to different situations.”

7. If hired, what role would you like to play at Cloudflare?

This question is a great way to determine what the candidate’s goals are and how they plan to achieve them. It also helps you understand their career aspirations, which can help you decide if Cloudflare is the right fit for them.

8. What are some ways that we can improve the security of our systems?

Cloudflare is a company that focuses on security, so it’s important to be able to answer this question well. You can use your knowledge of the company and its services to provide an example of how you would improve the security of Cloudflare systems.

Example: “One way we could improve the security of our systems is by using two-factor authentication for all employees. This will ensure that only authorized users have access to sensitive information and files. Another way we can improve security is by implementing SSL certificates on all websites. These certificates encrypt data between servers and browsers, which helps protect against cyber attacks.”

9. Describe a situation where you worked under pressure and met deadlines.

When answering this question, it can be helpful to provide an example of a time you worked under pressure and how you overcame the challenge.

Example: “In my current role as a web developer, I was working on a project that required me to create a website for a client who needed it completed within two weeks. The client also wanted several additional features added to the site, which would take more time to complete. I met with the client to discuss their expectations and what they were looking for in the website. They agreed to pay extra if we could get the website done by the deadline.

I then gathered all of my team members together to discuss our options. We decided to work overtime each day until the website was finished. It took us three days longer than expected, but we got the job done and delivered it to the client.”

10. What has been your greatest professional accomplishment?

This question is a great way to learn more about your potential new colleague and how they view their own success. When answering this question, it can be helpful to discuss an accomplishment that relates to the job you’re interviewing for.

Example: “My greatest professional accomplishment was when I helped my previous company launch a new website in record time. We had a tight deadline of two weeks to complete the project, but we were able to do so with only one week left until the official launch date. This allowed us to test the site thoroughly before going live, which resulted in very few bugs or issues.”

11. What is your understanding of HTTP/2 and its benefits?

HTTP/2 is a protocol that Cloudflare uses to improve the performance of websites. Your answer should show that you know how HTTP/2 works and what benefits it offers. You can mention some of its features, such as header compression, multiplexing and server push.

Example: “HTTP/2 is an upgrade from HTTP 1.1. It has many advantages over HTTP 1.1, including header compression, multiplexing and server push. Header compression reduces the size of headers sent between clients and servers by up to 60%, which saves bandwidth and improves page load times. Multiplexing allows for parallel loading of resources, so users don’t have to wait for one resource to finish before they can access another. Server push sends resources to the client before the user requests them, which also speeds up page load time.”

12. What do you think is the most important part of working as a team member?

This question is an opportunity to show your leadership skills and ability to work with others. When answering this question, it can be helpful to highlight a time you worked well as part of a team or helped another employee succeed in their role.

Example: “I think the most important part of working as a team member is communication. I believe that if everyone on a team knows what’s expected of them and how they can contribute to the company’s success, then we’re more likely to achieve our goals. In my last position, I was tasked with creating a new marketing campaign for one of our clients. I met with my supervisor weekly to discuss progress and ask questions about the project. This allowed us to create a successful campaign that increased sales by 20%.”

13. What are some challenges you might face when trying to sell to a technical person?

This question is a great way to show your ability to work with people who are not in the same industry as you. You can use this opportunity to demonstrate that you have experience working with clients and customers of all backgrounds, including those who are more technically inclined.

Example: “I’ve worked with many technical professionals throughout my career, so I’m used to having conversations about technology that may be over someone’s head. However, I always try to make sure that everyone understands what I am saying and how it relates to their business. I also like to ask questions to ensure that they understand everything I am telling them.”

14. Have you ever worked on a project that failed? How did you manage it?

This question is a great way to show your problem-solving skills and how you can learn from past mistakes. When answering this question, it’s important to be honest about the failure but also highlight what you learned from it.

Example: “I once worked on a project that was supposed to increase website traffic by 50%. However, after implementing the changes, we saw no change in traffic at all. I spent several days researching why there wasn’t any change in traffic before realizing that I had forgotten to update one of the settings. After updating the setting, we saw an increase in traffic.”

16. What is the most compelling reason why someone should use Cloudflare’s services over a competitors?

This question is a great way to test your knowledge of Cloudflare’s services and how they compare to other companies in the industry. You can use this opportunity to highlight any specific features that you have used or are familiar with, as well as why you think they’re beneficial for users.

Example: “Cloudflare offers some of the best security features on the market today. Their free service includes SSL encryption, which protects against cyber attacks and data breaches. They also offer DDoS mitigation, which prevents hackers from taking down websites by flooding them with traffic. This feature alone makes Cloudflare one of the most compelling options for businesses looking to protect their online presence.”

17. Can you explain the process of domain name resolution?

This question is a great way to test your knowledge of the DNS process. It also allows you to show that you can apply your knowledge to real-world situations.

Example: “Domain name resolution is the process by which a domain name is translated into an IP address. This happens when a user types in a website URL and it’s sent to a DNS server, where it’s resolved into an IP address. The IP address is then used to connect the user to the correct web server. Domain name resolution is important because it helps users find websites more easily.”

18. What are some common mistakes made when securing web servers?

This question is an opportunity to demonstrate your knowledge of web security and how it can impact a company’s bottom line. You may want to mention some common mistakes you’ve seen in the past, as well as what you would do differently if you were tasked with securing servers.

Example: “One of the most common mistakes I see when securing web servers is not updating their software often enough. This can leave them vulnerable to cyber attacks that could result in data breaches or downtime for websites. Another mistake I’ve seen is using weak passwords on web servers. Weak passwords are easy to guess and crack, which makes them more susceptible to hackers who use brute force methods to gain access.”

19. When do you know if a product or service is ready to be deployed?

This question can help the interviewer determine your ability to work independently and make decisions. Use examples from past experience where you had to decide when a product or service was ready for deployment.

Example: “In my last role, I worked on a team that developed new features for our website. We used Agile development methods, which helped us create small batches of code that we could test before deploying it to production. This allowed us to deploy only what we knew would be successful in terms of functionality and performance.”

20. Name a few technologies you used to develop software applications and tell us why you chose them.

This question is a great way to assess your knowledge of cloud computing and the types of applications you’ve worked on in the past. Your answer should include a list of technologies you’re familiar with and why you chose them, along with an example of how they helped you complete a project.

Example: “I have used Java, Node.js and Python for my last three projects because I enjoy working with open source software that’s easy to use and free. These languages are also highly scalable and can be used to create web services or other online applications.”
