Adwizar interview questions

There were 3 interviews. 1st one was a "group interview. The 3rd was with Spectacular the CEO and 2 others. The interviewer pushed my interview back each time by 30 minutes to 1 hour with very little notice (just before the interview). After the 3rd interview, I was offered a position via email and was told to expect a written agreement within 72 hours, and if but received, to email a specific person. I did not receive the agreement t and emailed the person as directed with no reply. The agreement was emailed 2 weeks after. I signed the agreement the same week and it's been about a month. I still have not received any communication.
