Organizations hire site reliability engineers to save the company money and time by improving the systems and processes used to develop and implement software applications. During an interview, you will be asked how you accomplished this in the past. When preparing for the interview, you should have some very specific examples of process improvements you've implemented in your previous roles. You can describe these using the STAR framework. Describe the Situation, talk about the Task you were trying to complete, discuss the Actions you took, and finish with the Results you attained.
