CalAmp Account Executive interview questions

I was contacted by a recruiter via LinkedIn regarding an AE role. I accepted his invitation for a meeting to discuss the role and blocked time off of my calendar to meet with him (Keep in mind it is end of month and every minute counts while I am trying to close business for my current role). I received no call, no notice, nothing until 16 minutes after our scheduled time. I found this to be extremely unprofessional and if it is any reflection on how the company operates, I have no interest in pursuing a career with this company.
