Thanks for answering the previous person's questions; your answers were very helpful. Can you talk about how long it takes most people to reach staff level (or how long it took you)?

At what level do most engineers plateau at Google (meaning most people are unable to go past it)?

I came into Google as Senior with about six years experience at another large tech company (where I'd also made senior recently).

Senior (one level below Staff) is deemed "career level," and if you just want to build stuff it's a good place to stop. Staff involves a much more substantial leadership and coordination component, and that requires both the skill and desire to take on that sort of work.
