Pros
Still a reasonably good working climate, but recent changes have eroded it. The company always had a challenge in the market and people had to deal with times of success and near-disaster, but culture held people together. A number of those things have eroded and made it more challenging, but the essentials are still there. Career growth has traditionally been good and many people make a career in the company. Its also professional without being stuffy, and has a global presence. It also has had a strong community and social presence, which is a motivator for many employees in the company.
Cons
If you're looking for financial stability, look elsewhere. The company has short periods of doing well and longer periods of not doing well at all. You have to be willing to work at a place that has risk. If you're in the Bay area, the company has definitely shifted to Texas in the US and other places in the world, so if you want to grow, you may have to move from the valley. There's also been a lot of change so morale has taken a hit. The purchase of ATI put a lot of strains on the Company, which impacted the financials and the culture.
