Robert Half Contract interview questions

Sent resume and got a call next day strongly requesting a skype interview. Told them I was looking and not able to do a skype session at work. I could do it afterhours or weekend, but was told they dont work during that time. Asked if they would be willing to do phone interview, nope. Ok I am employed and since Robert Half makes the process difficult I told them never mind not interested. I was then told he would keep me up to date on any other offerings. ???
