Corporate levels actually start at 59 (there is no level 1 for example). Levels below this are generally for things like data center employees and non-engineering roles. Also ranges for each level can vary wildly from one org to another. The greater your orgs impact increase the likelihood of being towards the top of a range. This is also not necessarily what you want to shoot for because bonuses are where the real money is long term.

The bonuses are given out in two “chunks”. Cash bonus in September, then stock bonus is spread out and vested over a 5 year period. So that $50k bonus is not a huge check at once but can grow to be massive.
