You get the feeling of grad school, flexibility and you work with smart stimulating people.
Cons
The compensation and salary are mediocre, if you include inflation your salary increases by 1.5% after years of work. Promotions are not merit base, they are pressure base. As a young talented engineer I will leave as soon as my GC is cleared.
Mostly decent place to work in a bad neighborhood.
Cons
We have people who work 80+ hours a week and management loves them. Don't expect to get noticed for only working 60 hours/week. And you are not allowed to mark more than 40 hours/week in your timesheet.
