Provide an example of a time when you had to troubleshoot an issue with a cloud computing system you designed.

Troubleshooting is an important skill for cloud architects to have. Employers ask this question to see if you have the ability to solve problems on your own and how you do it. Use your answer to show that you are confident in your troubleshooting skills and can use them to fix issues with a cloud computing system.

Example: “When I was working as a cloud architect at my previous job, I had to troubleshoot an issue with one of our servers. The server kept crashing due to a memory leak. This meant that the server would crash after running for a certain amount of time. To troubleshoot this problem, I first looked at the logs to see what caused the crashes. Then, I used debugging tools to find out where the memory leaks were occurring. After finding the source of the problem, I fixed it by updating the operating system.”

If hired, what would be your priorities during your first few weeks on the job?

This question helps the interviewer determine how you plan your work and prioritize tasks. Your answer should include a list of things you would do to get started in your new role, such as meeting with team members, learning about company processes and procedures and familiarizing yourself with existing systems.

Example: “My first priority would be to meet with my manager and other key stakeholders to learn more about their goals for the organization and what they expect from me. I would also want to understand the current state of the company’s IT infrastructure so that I can develop an actionable plan for improving it. Finally, I would spend time getting to know the employees who support the company’s technology needs.”

What would you do if you discovered a critical flaw in the cloud computing system you designed?

This question can help interviewers assess your problem-solving skills and ability to make quick decisions. Your answer should show that you are willing to take responsibility for your actions, even if they lead to negative outcomes.

Example: “If I discovered a flaw in the system I designed, I would first try to fix it myself. If this was not possible, I would inform my manager of the issue so he could decide how to proceed. Depending on the severity of the flaw, we may need to shut down the entire cloud computing system until the issue is resolved. In this case, I would work with my team to find an alternative solution while fixing the flaw.”

How well do you communicate technical concepts to non-technical stakeholders?

Cloud architects often work with non-technical stakeholders, such as business owners and managers. These individuals may not understand the technical aspects of cloud architecture, but they need to know how it will impact their organization. Your answer should show that you can communicate complex concepts in a way that is easy for others to understand.

Example: “I find that I am able to explain technical concepts quite well to non-technical stakeholders. In my previous role, I worked with several business owners who wanted to know more about our cloud computing services. I was able to give them an overview of what we were doing and why we were doing it. They understood the basics of what I told them and asked questions when they needed clarification.”

Do you have experience working with large teams of developers and engineers?

This question can help the interviewer determine if you have experience working with a large team of developers and engineers. This is an important skill to have as a cloud architect because you will be collaborating with other IT professionals on projects. Your answer should highlight your teamwork skills, communication abilities and ability to lead others.

Example: “In my previous role, I worked with a large team of developers and engineers. We had weekly meetings where we discussed our progress on various projects.
