Bluewater Communications Group interview questions

Was called and briefly discussed my network experience. They said they would set up a phone interview within 2 to 3 business days. Waited two weeks to finally have the phone interview. The interview lasted approx one hour. I was asked about MPLS and how to configure it. Had to give the precise configuration needed on the routers.What kind of routers I had experience with ( Type and model of router). I was asked if VRF was needed. Was asked what kind of routing protocols were used with MPLS and to describe an example.
