Pros
Flexible work hours, some knowledgeable, smart and good personnel. If some issues could be fixed, it has a lot of potential.
Cons
This is for the Oil and Gas US group: Even for your own project, the boss may not share Information with you (discussion with clients) until specifically asked for. The interview consists of a test misleading you to believe technically challenging opportunities ahead, but may simply turn out a task of lots of data entry from drawings. Quantity is more important than quality. Overall misleading and dubious practices.
