I applied through a recruiter. The process took 2 months. I interviewed at Roche (Tucson, AZ) in Aug 2010
Interview
Very thorough process. If you make it to the final round of interviews, you will be flown out to Tucson to be interviewed by senior management.
Interview questions [1]
Question 1
The most difficult is being able to explain how you have built value for a customer in your previous employment. Ventana places heavy emphasis on building value within the customer.
