Ok..I have not even started working. I'm newer than you..just signed paperwork against my better judgment.
BUT the info I got was...there are six levels at KGS. There is an approximate $4,500 to $6,000 difference in each level. The first level is 36K ($17.34). Second Level is $40.5K ($19.48). and the level six is about $65K ($31.25 an hour).
I "interpolated" the intermediate levels, as 3) $46.5k 4) $53K and 5) $59k.
I was told by the recruiter...that no increases from level one are ever done in first year (or likely two)....but bonuses...are used to recognize meeting higher levels. It is only after sustained performance at a higher level that you will be moved up. I took that to mean like 9 months.
I too surmised the bonuses were bologna, a vague figment....and were easily evaporated on a whim.
