What is the longest survey you have ever done?

The longest survey I have ever done was probably like 10 minutes, not that much. However, the thing is, I got rejected, so I never attempted to do surveys again, but if you do them, what is the longest survey you have ever done? I would love to hear!

Maybe quite similar to yours, I have been completing surveys to earn some extra money. While the earnings may not be significant, I am happy for the opportunity to make some money from participating in surveys.
