- Remote work used to justify overwork including weekends
Bottom Line

Choose Fireworks AI if you want to work with ex-Meta AI infrastructure engineers on cutting-edge LLM inference — but expect early-stage startup intensity and limited structure.
Samsara
Strong sales culture and real-world product impact at massive scale, but engineers report significantly worse WLB than the company average suggests.
