Comperex ERP Consultant interview questions

After sending an application I got 2 interviews. The first one was in Raamsdonksvee, the second one in Antwerpen. After I entered the office the owner did saw me but let me wait at least 15 minutes before introducing himself to me and made me feel not respected. My first impression was that he is rather full of himself and gave me a feeling that was making me not comfortable. But it was a good interview afterwards I thought it was maybe only the moment. I did accept the offer with a raise in the future, but that was never granted in the end.
