Give feedback on the "Feedback & 1:1s" tab by clicking the “Feedback” button next to one of your team members’ names. By default, your feedback is private between you and the receiver.
A feedback session contains of an optional general comment and structured questions about your colleague - these questions depend on your company framework and the team(s) that your colleague belongs to. For each question, you can pick a level of proficiency on a continuous scale and add a comment, if you want. If you’re not sure about something, you can also skip that question.
