Pros
Entegris has very interesting technologies and is growing and investing in technology development in the MA area, which is great for career growth and job security. The company is relatively small and has a diverse work force. The employees are friendly, hard working and dedicated.
Cons
The company culture creates a difficult environment to work in. They provide very little training and are very disorganized, which makes it hard to do your job. Half the battle is figuring out how to do a simple task. The culture does not support work-life balance. HR pushes their "honor system" vacation policy as being a great perk for employees, but the culture makes you feel guilty for using it. And since time off isn't tracked (for salaried employees), you don't have the benefit of earning time or being paid out if you don't (or can't) use it. Departments have a CYA mentality, which leads to the blame game and they lack a spirit of collaboration towards a common goal.
