Who are the main cloud service providers, and which ones have you worked with?

This is a very basic general question that can be asked at any time during the interview. Many hiring managers have not been trained in interview techniques and will ask various types of questions at different times during the interview. This unstructured interview style may be distracting, so you need to stay flexible throughout the interview. As always, keep your answer to this question brief and to the point and anticipate a follow-up question or two.
