Pros
(Not saying whether I was software or data science, but I will say that I was intimately involved with both types of work) -Fantastic people for the most part -There were some pretty sharp people there, you could learn a lot about petroleum engineering from them
Cons
-It's been awhile since I've been there, but when I was, it was a joke about how the company is Theranos for the energy world. I've heard secondhand of us showing completely falsified data to some very well known companies -Absolutely zero direction. -*Extremely low* compensation for the caliber of people. I tripled my salary after leaving -The lowest amount of rigor I've ever seen in an organization that was trying to do 'science'. Some of the ideas I heard on how to solve a certain ML problem were almost laughable, until you realized that they were being serious (and these ideas often came from upper technical management!)
