Pros
The average competency and intelligence in this company is substantially above any other company I've ever been at. At prior companies, i struggle to explain basic metrics and concepts to business people. At ethos, everyone just gets it which i was very surprised at. Everyone is super sharp, and is an amazing environment to learn from. Stakes are high for analytics team because major product & business decisions are taken from the analysis. This actually stresses me out sometimes, but it's better than in prior jobs where i will work on some analysis, only for the management to take a decision that was literally opposite of what i recommend.
Cons
Get ready to work hard and work fast. You better be smart and ready to go. the environment at ethos is that if you are not at the bar, you are out quickly. There's no prisoners taken here. I personally think this is a good thing, but i know it causes many people stress who are not ready for it.
