Milestone Technologies Project Coordinator interview questions

A few weeks after applying as a Project Coordinator at Milestones Technologies, I received a voicemail from a recruiter asking to call him back regarding this position. So I called back at around noon the next day and nobody answered. At first, I assumed the recruiter was out to lunch and left a voicemail. I tried again the next few days and at different times and I still was not able to get a hold of the recruiter. In the end, I had to give up on it due to the non-responsive recruiter. To sum up, I got a phone call back regarding my job application but was not able to contact the recruiter after many attempts.
