Wound Care Solutions interview questions

I went in to interview a couple of times with the same manager. Both times upon arriving he was unable to see me and they attempted to scramble together an interview with someone who was entirely unprepared to see me. The interview itself was easy as can be, but I can imagine that was mostly because the person had absolutely no time to prepare for me. Their response time from HR was great, and very helpful, but overall I felt the company was simply too unorganized to switch too.

I was scheduled for an interview last week at 330. I waited about 20 minutes and there was no reply so I called them. No one answered and I left a voicemail so we could set a time to reschedule for next week; I sent an email as well and no answer. It's been three business days and their recruitment advisor has not called since. This is completely unprofessional and am frustrated with the waste of time this company has put me through.
