Here's what my comp has looked like at FB over the years:

2012: ~75k (internship + first half of sign on bonus + relocation bonus)

2013: ~100k (salary for ~6 months + second half of sign on bonus)

2014: ~225k (~110k base salary + stock)

2015: ~265k (~130k base salary + stock)

I believe myself to be around average. From what I've heard about some of my peers' comp they sound comparable to this as well.
