Pros
Best culture I've experienced - I've worked at Microsoft, Disney, Accenture and others. I was leery of joining because I'd read the NYT article about how messed up their culture was. My recruiter asked me to make my own judgment and not let someone I didn't even know decide for me. Great advice. I asked hard questions, got honest answers and decided to join. I'm so glad I did. I work 40 hours per week with teammates who are caring and supportive. I've never been asked to work an evening or a weekend. People collaborate with me and we share credit. Folks are open and transparent, with a culture that values honesty over politics.
Kontras
I think to be an L8+, it would be hard to work the way L7 and below do. I've seen the work schedules of the L8s and I wouldn't want that. But, given that I'm not an L8, I'm perfectly fine with where I am and my work-life balance. For someone who's more hard-charging than me, they might have to pay a higher price in terms of work hours.
