Went through six interviews, each interview was included technical knowledge about ports and protocols used for connecting to machines. For the last interview that I had, I had shown up for the interview and after waiting half an hour was finally told that the manager had forgotten about the interview. No apologies were given, and when I asked about rescheduling, was told that I would be contacted to reschedule( and was never contacted afterward). Completely unprofessional and would avoid.
