I effectively have 100% work from home for a FANG. I live in the Midwest and my compensation is the same as engineers working from HQ. I worked from HQ for a few years then told my manager I was gonna quit to move closer to family and we ended up being to arrange this. I fly to HQ a few times a year to have face time with my team. Not sure how long this arrangement will last, but it’s been awesome so far.
