Responding to a survey is easy! You'll find the surveys in the 'Survey' app, the newsfeed, in your notifications or through an invitation to respond in your emails inbox. In either case, click on the link - 'Take this survey' - and the survey will open on the platform. If you're not signed in yet, you may be requested to do so.
The rest of the process speaks for itself. Don't forget to click 'Submit my responses'.
Depending on the settings chosen by your administrator, you can change your answers after submitting your responses.
The Survey app will also show you an overview of all previous surveys that you had permission to fill out.
