If you are moving into a Career Ladder or Non-placed role there will not be a promotion associated with starting the new job. If you were selected for a Placed position at a higher PSG the promotion should be effective the day you start the new job (October 1st for most Wave 2).
The next “normal” promotions will be decided ~November and be effective in March. These are expected to be extremely rare this time around.
The default is a 5% raise with a promotion in most locations but it’s not a hard rule.
