If you are interested in compensation numbers and have thick skin (its anonymous so there is a lot of racism/sexism/bullshitters/negative hostility and more), I recommend getting the mobile app blind as there is a ton of this information there. I will regurgitate some of that information here for you though.<p>For level comparison at different companies, lots of people point to <a href="http://levels.fyi" rel="nofollow">http://levels.fyi</a><p>Here is a compensation poll for amazon employees only based on job title and level with 161 responses: <a href="https://goo.gl/V9QKHh" rel="nofollow">https://goo.gl/V9QKHh</a><p>The total compensation rages I have heard for Amazon are 145k for new grads, 170k-230k for SDE 2, 250k-350k for SDE 3, 400k-600k for principal engineers. There are 2 more levels after that but have not really seen any data for those levels.<p>Here are Facebook's total compensation numbers quoted from "fmwf":<p>E3: 107K-125 Salary, 40k stocks a year, 10% bonus.<p>E4: 140k-160k Salary, 70k stocks a year, 10% bonus.<p>E5: 170k-195k Salary, 120k stocks a year, 15% bonus.<p>E6: 200k-220k Salary, 200k stocks a year, 20% bonus.<p>All Facebook numbers assuming expected performance if you kill expectations you get more (25%-200% more shares).
