Booz Allen Hamilton interview questions

HR Recruiter called me to discuss the position and asked me to come in for an interview the following week. Interview lasted 2 hours at one half hour a piece talking with 4 teammembers. the interview went really well and I left thinking I had a great opportunity at moving forward. The HR Recruiter said I would definately hear from him by the following Tuesday. He has since disappeared. He has not answered my phone calls or emails regarding this position. I feel that the follow through portion of this process was handled awfully.
