XPO Analyst interview questions

Applied online and was immediately contacted by a recruiter, who left a message for me. I returned his call the same day. It took over 7 days for him to contact me again. Unfortunately, I missed his call and he left a message. I again returned his call same day but had to leave a message. I've followed up several times with no response. On my last attempt to follow up he answered the phone and quickly told me he didn't have time to discuss that position right now and he would call me back tomorrow. He has never returned the call. In my eyes this is completely unprofessional. At least have the common courtesy to return the call and explain the companies position.
