Nina Naustdal interview questions

Sent the company an email with a copy of my cv and online portfolio and was invited for an interview. When I arrived to the showroom for the interview, one fo the interns who let me into the showroom area asked if I can come back at a different time as the designer was not in to interview me. She had no clue what was going on regarding the interviews for this internship position and it did not look like they even knew I was coming in for an interview, which was very disappointing. When I returned later in the afternoon for my interview, the designer looked very disorganised and did not know what to ask me. It seemed as though they already knew they did not want to hire me before I even started talking. What was even more disappointing was the fact that they stated they would respond in no more than 2 days after the interview with their decision, they in fact did not email back at all and I had to email them about their decision, to which the intern replied stating they had already chosen an assistant. This company is very unprofessional and disorganised, DO NOT WASTE YOUR TIME!
