It depends on how long ago you did it as there is a time limit on the validity of the P&S for all airlines within the group. I think 18 months to 2 years. Can't remember............
Assuming you are "current" it then depends on what your overall grade was.
Therefore, if you're "current", and your overall grade is above the minimum required for Eastern, then you won't need to do the P&S again. You will need to do a sim and interview however.
