Network 1 Consulting interview questions

Additional application online required and personality test. Then scheduled phone interview. Sent interviewer confirmation for time and date in email. Then told, not that time and date when I contact them at agreed time and date. Given new time and date. Again, no contact, on another call. Then left message. Sent follow up email to reschedule, no response. Waste of time. Apparently just going through motions to satisfy management.
