The process for most Stryker roles is HR - Gallup - Hiring Manager - Panel - Department Head - Final offer. This is pretty standard across sales orgs. at Stryker.
I applied through an employee referral. The process took 3 months. I interviewed at Stryker (Phoenix, AZ) in Apr 2013
Interview
Interviewed with senior leadership team and took a Gallup leadership profile. Met with the current sales director and the Vice President of Sales. I was asked to develop a plan to help the region exceed sales goals, which consisted of people talent rank, performance rank, and pain rank if I were to lose a team member.
