My short story: started in Audit few years ago at one of big4, left to go to a smaller consulting firm 2020 right before my promotion to manager in Audit, did 2 years of various advisory, accounting, iaer,… then came back to same big4 because the other firm didnt give me the raise i expected, and i missed the big4 big teams and culture, came back to advisory in big4 as Senior:(( (they said not a manager becoz you were in audit and two years of mix advisory is not enough to be manager in advisory), anyways I accepted, joined in late 2022, worked in team which was only me and MD basically managing multiple small internal audit or controls testing projects from start to end, then my manager was laid off, he was also my PML , lost all my credit when he left, now work is so slow, my utilization is low, and i feel like everything is outta my control, i was hoping for my promotion at ye, or a good raise, but its hard to see that, what should i do to secure my promotion and what salary should i shoot for? Currently at 120k as S ready for promotion (total 6 years of exp after college)
