The first thing you will notice when you over knead a dough is that it will feel very dense and stiff. It will be hard to press the dough down and flatten it on the counter. It will also be hard to knead by hand and resist being re shaped. The dough will likely rip easily rather than stretch when pulled. When the gluten has been over developed due to too much kneading, it will be tight and have almost no give. If this describes your dough, you have definitely over kneaded!
