Groupon Administrative Assistant for Sales Development Team interview questions

I applied on line for several jobs at Groupon that I felt were a good fit for me. Approximately 2 weeks after my application for Administrative Assistant for Sales Development Team was accepted I received a phone call from a corporate recruiter. She set up a phone interview for the very next day at 3 pm. After not hearing from her by 3:15, I called and left a voicemail. I also sent an email stating I was still very interested and would love to reschedule....didn't hear back until that Thursday, informing me she would be out of town for the rest of the week. After responding to the email and telling her my availability that very day, I finally received a response via email the following Tuesday morning, asking if I was available for a 2pm interview the same day. Once 2:15 passed, I called and tried to leave a voicemail and it didn't go through. I'm sending another email today, because for some odd reason...I'm still interested in working for them! Anyone else have a similar experience?
