Pros
Zeeco is very good at recruiting talented and dedicated employees. Pay is good for entry-level engineers. Interesting industry, and good opportunity to gain experience quickly.
Cons
My peers and I have come to describe employment at Zeeco as an abusive relationship. I have a dozen stories of former coworkers, GOOD employees who were pushed to their limits, given unsavory assignments far outside their job description, asked to behave unethically, unfairly compensated, etc. Personally, I was heavily overworked and made to feel that the world would collapse if I did not consistently put in long hours at the expense of my family. I observed a tremendous lack of appreciation toward countless coworkers who also worked long hours and made a lot of sacrifices for a company they felt a sense of loyalty toward but who did not return that same loyalty to its employees.
