Very unprofessional. I applied for the job and in about 2 weeks I received an email to schedule a phone interview. The email was very unprofessional and from an intern, which didn't bother me at the time. I scheduled the interview and the job interviewer called me 15 minutes late. I found this a very negative start. TO follow this negativity, he was also an intern. He was very dry and not knowledgeable about the position at all. I asked questions at the end and he didn't know the answer to any of them. He stated he would email me answers in a few days, well guess what, I never got an email! He even mentioned the job title, which was wrong, he didn't even know what job I was interviewing for! To me this made me absolutely not want to work for the company. It made me feel unwanted and unimportant.
2 weeks later, I got a rejection letter from another intern that was the most unprofessional rejection email I have even been sent. It was one line that said, unfortunately you have not been selected.
The company should really treat applicants like they matter.
