Avantages
Broadcom is not very bureaucratic, it's OK to work with multiple business units, and the engineering/marketing division is less pronounced than most. There is very good internal communication, so various projects can share IP and ideas. Compensation (cash) is OK, but the equity-based compensation (RSUs mainly these days) is unusually good, and the patent rewards are generous. Perhaps the best part is the high quality of the rest of the staff.
Inconvénients
It's a bit chaotic, so it takes a while to learn how things work. The company makes lots of acquisitions, and tries not to mess with the new group's internal processes too quickly. This means there are many different working styles and tool chains that need to be integrated over time.
