Narrative and your review based pretty much on what the engagement manager made of your work ( and equation with him).
Do a fabulous job, get rave reviews but if you aren't the fav ... you will get the medium average rating.
Find your own way to get noticed, extraordinary efforts to get even slight recognition. Also luck of the draw.
Salary is what you bargain when you join. After that you can forget about anything more than a few hundred dollars bump for 5-8 yrs (unless you get promoted , which is a huge effort and favor that you will be made to pay for)
