I applied through an employee referral. The process took 2+ months. I interviewed at Certiport Inc. (American Fork, UT) in July 2014
Interview
Other than the whole process spanning over several months, I had a great experience interviewing for the position. Everyone there was extremely nice and professional. They also were willing to help you get the certification they like you to have if you didn't already have the certification.
Interview questions [1]
Question 1
General support/technical scenarios and what you would do (or have done) in those situations.
