Can you explain how Service Level Objectives, or SLOs, are used in the work of a site reliability engineer?

Service-level objectives, or SLOs, are one of the fundamental tenants of the site reliability engineering profession. Therefore, you should have a great deal of knowledge about these and be able to discuss them at length. The interviewer at Google knows this and is looking for a direct answer from you. Your response should provide an overview of SLOs and a brief description of how they are used. The interviewer will ask you a follow-up question if they need more information.
