Brand new to blender and imported a model from another program. Went into edit mode but not seeing any option for vertice, face, edge selection? Am I missing something here?
In this moment the mesh is selected but the Metarig is Active (last selected, even if it's hidden). So you are in edit mode of the armature, not the mesh.
In object mode, press Alt H to unhide everything, click on the 3Dview background to unselect everything, then click on the character (it has to become yellowish, not orange), and go to Edit mode.
