Hey there! Unless you are being considered for a leadership position, you do not need to have examples for the first point. And if you’re interviewing for the general SDE 1 role (entry level software engineer) they are slowly moving away from asking leadership principle questions. However, it’s always best to be prepared, and we recommend reviewing this doc for more ideas: https://docs.google.com/document/d/1r5TOkXhJsW4t1gCjdOKNEsQDIKbVJ1q8L4NZvwJ5SkQ/edit#
For Insist on Highest Standards, think about any times you’ve thought of an improvement to a project (whether it was on your own or in a group), and why you felt it was important to change. You can also use examples from previous jobs/internships, even if they weren’t related to engineering.
For Earn Trust, think about any times you’ve collaborated with a team of new people, or an individual person. What were the things you did to build a working relationship with them (ie setting up meetings, communicating over email) and how you showed them that you are a good working partner (ie completing work on time, sending updates)?
