Pros
One of a kind technology and product line. If you are interested in Robotics and Surgery there is no other company in the world that does what IS does. Excellent, caring and friendly work environment full of very smart people who are at the top of their field. You get to go home everyday knowing what you do actually improves patient's lives - sounds like marketing speak - but it is true. I have had a da Vinci surgical procedure - a Fundoplication and Hernia repair - where I spent 2 days in the hospital and was back at work 4 days after my surgery.
Cons
Located in the very heart of Silicon Valley the commute can be a grind - but it is close to Caltrain if you can use it. If you are overly title-conscious or are looking for a place solely to climb the corp ladder IS isn't the place for you.
