I was E6 at Facebook for 1.5 years.

Left due to a combination of not finding the right team/project and constant pressure to work on something impactful rather than fixing existing issues I cared about. This seems to be a common issue at FB with senior engineers joining and having to ramp up quickly (2 of the senior teammates left while I was there for the same reasons).

Currently at WeWork where you don't have to write multi-page assessment of all the impactful things you've done during the last half.

It's not perfect but the work-life balance at senior level is better than at FAANG.
