Affirm IT Security Analyst interview questions

The interviewer was late for the appointment, which gave the impression of mad seriousness. The interview consisted of general questions without any depth. After telling me that I had a solid knowledge of security, the answer was negative to continue the process in the following days. The explanation from HR was null and void. After sending them an email again asking for the reasons, to my surprise the answer was vague and general. P.S. The interviewer himself, who seemed totally inexperienced, acknowledged the high internal turnover of departures in the company, which makes me suspect the lack of seriousness of the company. Possibly one of the most ridiculous interviews.
