As a participant, you will receive an email asking you to answer a number of questions. Just click on the link in that email to start answering the questions - a login is not required. If you are traveling, you can answer these questions from your mobile. Finally, if you are currently logged in, you will also see a notification on the "Me" tab.
Questions/statements are answered with a quantitative score ranging from 0 ("not at all") to 10 ("absolutely") and/or an optional qualitative comment. All answers are optional.
If your survey is set up to be anonymous, you will see a clear hint guaranteeing your anonymity - in that case, your answers will be (and stay) completely anonymous - you can learn more about how we guarantee your anonymity here. We also enable non-anonymous surveys or check-ins; they will be clearly marked as such.
Each survey round is open for 14 days, so you can still participate if you've just come back from a holiday.
