Service level objectives and service level indicators are the keystones of the work SREs perform. Interviewers at Google will be interested to learn how you go about establishing these and whether you are open to changes once the project is underway. They're looking for a balance between commitment to the metrics used by SREs as well as the flexibility to change when circumstances demand it. Your answer should demonstrate a systematic approach to establishing the criteria used to measure the success of a project while also showing that you can adjust projects as they move forward to optimize them.

"When scoping and planning a new project here at Google, the first thing I would do is understand the service level agreements project stakeholders are looking for. This helps me establish the service level objectives which will result in the SLA being met. Once I have SLOs set up, it is relatively easy to build a list of service level indicators that will tell the Google project stakeholders how the project is progressing and if the SLOs and SLI days are being met. I've found that a top-down approach works best. I'm also open to adjusting the SLOs and SLIs if it is determined that they are either too liberal or too strict and will not result in a predetermined SLA."
