What should the pose of the uploaded rig be?

The rig should be orientated to the FRONT view with its face, along the UP axis with its spine, standing on the floor:

Blender: looking along the -Y, +Z is up, the floor is X, Y
Maya: looking along the +Z, +Y is up, the floor is X, Z

It doesn't matter if the rig is A, T, or any other pose as long as the conditions above are met.
