US Tech Solutions Staff Analyst interview questions

The interview was about a 15 minute phone conversation. We didn't actually talk face to face. The actual interview with the contractor was horrible. I was told by US Tech that I was interviewing for one position and interviewed for a totally different position. (US Tech Solutions had submitted my resume for two separate positions.) I was extremely confused as to the questions they were asking me until I finally asked what position I was interviewing for. Was actually surprised that I was contacted to accept the position as my interview was that bad.
