Reliant Energy Financial Analyst- Small Business Division interview questions

I applied for the position online and wa invited for a phone interview initially. This graduated to a face-to-face interview with 4 people over a 3 hour interview at their office the following week. They seem to like working with one another but are evidently encountering some resistance from some employees in other departments who do not want to provide critical information in a timely matter. I was asked 4 times "How do you deal with difficult people?" Their questions were very indicative of the recent purchase of Reliant by NRG.
