Excel Systems Dynamics Ax Developer Part-time Position interview questions

I called for interview process for part-time position in the company office in Al Giza and we planned the Interview after 5 days when I attended the interview on time the HR specialist said the technician person have an emergency and he left the office (a small note I consumed 2 hours to reach the office which is better if she calls me and schedule another time) the she said he (the technical interviewer) will call me tomorrow at 1:30 pm The she called me to reschedule it to 4pm, but don't call me tell now so I don't recommend this place at all as they don't respect candidate Time or effort .
