When I passed the input dataset and tried to get the predictions, all the predicted values were identical! This confused me a bit and was wondering whether my understanding of the Neural Network was wrong.

You should really provide code for us to help. I would initially
suspect that you didn't use a linear function between your hidden
units and the outcomes.
Also, using 3 hidden layers and 6 units per layer is a bit much for
your data set (30-40 samples). You will probably end up overfitting.
