I applied through an employee referral. I interviewed at Pearson (Tulsa, OK) in May 2010
Interview
Talked to several people on the phone before my formal interview (a manager, a VP, an HR recruiter). On site interview lasted a day and included some panel interviews with different groups and one-one interview with the position supervisor and a representative from upper management. I was also required to give 30 minutes presentation on my research.
Interview questions [1]
Question 1
Nothing unexpected or difficulty. They expected you to be able to speak about the technical an interpersonal skills required for the position.
