The model is subdivided once and we work on the shapes either with the Move tool or the sculpting tools such as Zadd (emboss) , Zsub (engrave) etc.
Use the Smooth mode of the Draw tool to soften detailed areas.
When happy with the results, the model is exported to Maya to define selection sets.
With ZBrush it is of course possible to save user interface settings (Save UI) in the Preferences rollout but we can also set the 3D axis when importing/exporting to make sure the model is correctly oriented both in Maya and Zbrush.
