Give feedback on the "Instant Feedback" 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.
