You should share that data, help your fellow job hunters.
Last time I worked at a BigTechCo, salary ranges were $85-100K for juniors, 120-130 mid-level, and 150-165 for senior devs. Bonuses tend to hover around 30%. Of course, stock grants varied widely.
The largest IC pay I saw was $2M/year for a someone who years ago was part of a famous project -- semi-known guy. More recently, I've seen (indirectly) BigTechCo's offering $300-350/year total comp to mid-levels, and 5-600K to seniors.
Anyone else wanna share?
