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.

William Swansen

"The service-level objective, or SLO, is a metric agreed on by the service provider and their client concerning what objective the project will attain. This is part of the service level agreement, also known as an SLA. Common criteria used to establish the SLO includes response time, throughput, frequency, and other service delivery metrics. I insist on very specific SLOs when initially scoping and planning a project."
