Kforce Recruiter interview questions

I went into KForce applying for a job they were recruiting for. Instead of proceeding with that interview, they asked if I would be interested in interviewing with KForce as a recruiter instead. I agreed, and went through 3 interviews over the course of 1.5 months. After going through this rigorous process, they did not even bother calling me to inform me if I had gotten the job. It was frustrating to deal with this, as it was not even the job I had originally applied for and felt like a big waste of time. Additionally, as a recruiting company that specializes in this industry, you would think THEIR own staff would have the decency and professionalism to inform a candidate of their decision after a lengthy and time consuming interview process.
