Pros
I joined Boston Scientific at the time it was Guidant Corp. The main reason was that Guidant/CPI was a well established company with market share close to 50% - catching up with Medtronic. The bonus was rarely below 15%, and when they hired me, they decreased the salary by 15% expecting it to always be the case. Anyway, the pros were great bonus, opportunity to advance in medical device industry by learning new technologies.
Cons
Unfortunately the pros disappeared since the time of merger. Since the time Boston Scientific has purchased Guidant, the stock plummeted and never recovered. BSC is the loser in the war with Medtronic and St.Jude Medical. Engineers are overwhelmed with work, layoffs happen every year now since 2008, sometimes twice a year. There are too many managers who do nothing but meeting with employees just once a month. Bonuses are small or non-existent. Advencement/promotion is imposible
