The company contacted me when they said they would, and asked typical phone interview questions. These were things like willingness to relocate, why I was interested in BT, etc. The interview lasted 15-20 minutes and went about average, but the interviewer appeared to be in a hurry and no second round interview was given. I believe they had a large number to screen, so that is something to keep in mind - something really needed to stand out about the answers to get selected.
