Thomson Reuters lives and dies by the STAR Interview process. There are many sites that can walk you through these types of questions. Review and practice how you answer these questions, it really helps when you are in the interview. First an HR recruiter does an initial phone screen; Second a Team Leader does a phone interview, about an hour; Third is a tour of the office, shadowing a call center employee and then interviewed by a Team Leader and Product Leader. It is about a three hour long process on-site.
