Pros

I want to give zero star but 1 is the smallest

Cons

Terrible! I worked in Boston office and the cultural is toxic. Working hour is much longer than the industry. People sometime need to work overtime that is due to senior management bad schedule. Wouldn’t get any appreciate and no overtime paid bonus. Salary is lower than the industry average but highly demand on the work. 5 days on site work. No flexibility. Stay as far as possible!
