Jconnect Infotech interview questions

wanted me to apply for a contract role with an undisclosed prime vendor and an undisclosed end client. it took multiple conversations to finally get to the information. Then we agreed on a right to represent and rate. I signed off on it. 5 minutes later they wanted to lower the rate 6%. I rejected that. Then they want to withhold my first paycheck for over 60 days from the end of the starting month. i rejected that too. Then they had 4 more recruiters call me with similarly insulting approaches.
