There's always something that's not perfect, no matter where you work. If you found yourself outside of the clique, you will still enjoy your work, although you will seem like an outsider in the office on a daily basis.

With such a big headcount, career advancement and promotions don't come around too often.

Recently I was chatting with a few Silicon Valley Colleagues where we found ourselves discussing the various ways companies here in the Valley evaluate and review employee performance. Based on my experience from Cisco, and what I've learned there apparently isn't much uniformity in how corporate America evaluates and reviews employee performance.

It would seem to me that Cisco by far has one of the most balanced Employee Performance Review system in place. There are a few guidelines, however it's a culture based on trust. Employees are empowered and encouraged to define there career path with feedback from direct supervisors.

I have heard people telling that there is a lot of work pressure here and I accept that. But what the people don't know is there are many layoffs too. The bigger the company is, the more chances of layoffs are.
