Integrated Human Capital interview questions

They are a staffing firm so I had applied for a job with another company that was a client of theirs. The process was pretty standard, the agent was responsive throughout the process until the end. I filled out a packet with all of my info and answer standard interview questions to be added to their talent pool. She said she would update me on the next steps after forwarding my info to the client but never got in touch with me after that and ignored my email follow up. The office was very tough to find as it was in a large building with no signs.
