Pros
The upside at Bio-Rad is definitely the stability and compensation. If you want, you can work there for most of your life, having 3-7 different positions. Bio-Rad loves to promote and hire from within. Plus, with the company continuously doing well, buying the stock options is a big bonus.
Cons
This is where you've got to fight your inner demons with Bio-Rad. If you like latest technologies, products that release to market quickly (less than a year), then Bio-Rad is not your place. You've got relax here and go with the flow. The culture is even depressingly behind in standards by recognizing empty seats and not recognizing performance. Plus, if you feel Bio-Rad is a career between careers, well, be careful. Your skills may fall way behind depending on your background.
