Reviews originally posted on Glassdoor.
Very impact driven company. It's usually easy to tell if you're making a difference or not because everything is tracked
There are some very hardworking ICs doing all they can even without any career growth
Impact driven environment, if you make positive changes they will be noticed and recognized
