NIO Procurement Internship interview questions

I got a call from the HR and had an interview week after. This was almost a month ago and was told the HR will give me feedback in a week. One month letter and l still haven't heard from them, no rejection or acceptance letter. TOTALLY GHOSTED! However after reading other reviews here and knowing that its their behavior not to get back to applicants l am not surprised and it calms me down, This is really unprofessional.
