Do you have any practical experience creating technical documents and whitepapers for cloud technologies?

Even though you provided the interviewer with a copy of your resume detailing your experience, they still may ask you specific questions about the work you've done. They do this to confirm the information in your resume and make sure you're qualified for the type of projects they want you to work on. By asking this question, they hope you will provide examples of projects you've already completed similar to the ones they will assign you. Your research about the job and the organization should help you create stories about your previous work before the interview.
