Midwestern Dental interview questions

I filled out my paperwork while waiting a little scuffle between a patient and a professional that worked in the office it got heated in front of patients is could had been taken to a back office the patient got loud because he missed an appointment it was not good to look at not a good first impression. I almost considered to walk out. I then waited for 45 minutes to see the office manager I was on time for the interview, a little long to wait for an interview when you had a scheduled time. Went in for the interview sat down and was told the position was filled. You could not call me and had me sit there and waste my time, did not say that but thought it so if anyone who plans on working for this company make sure they have the position available might want to call seeing their staff does not seem to care about anything except making money extremely busy like a productions line. Would not want to work there. However I do need the experience in working in a office environment and this opportunity would had been a perfect start the wage offered was not good but that would of been okay I was going to stay to gain the experience needed to advance my career.
