Robert Half Senior Developer interview questions

They brought me in to their office in Irvine, CA to interview with a sorry recruiter claims to be a technical recruiter. Acted like a used car salesman. Was all over the place and drilled me on where I interviewed and with who. He wanted names and numbers too. He said he was using me to get names and numbers to help me out and not to double submit me. Ya right, when I told him I don’t remember he was like ok what about hiring manager you worked with. He boldly told me that he wants me to give him leads. After he wasted my time for an hour. They did not even validate my parking. It cost me $14 dollars and never heard back from him again. I emailed him and called him no reply. Scam staffing firm
