Express Scripts Legal interview questions

The initial interview was via phone with a man from human resources. He called late and only asked two general questions. After asking me questions about my background, he asked if there were any questions I had for him. I had 3 specific questions about the position, none of which he could answer. I asked him one general question about the position and luckily he was able to provide a detailed answer in response. The entire conversation lasted a little over 6 minutes.
