Anonymous Content interview questions

We had written followed by technical and hr interview. In my case, I had an extra technical interview at their Office (A s/w company which is in Guindy, Company which provides security services , SECURE services). Tech->hr->tech I had. While others had tech->tech->hr

Was told to contact a person who would escort me to the interview. That person did not match the phone number the company provided me and connected to a person in a completely different function. Was able to contact another person who escorted me to the interview. I was also told that I would be interviewing with one person, but the interview was a 3 on 1. A senior management employee was virtually silent in the interview, another had less than 1 year with the company and the third was the primary lead for the interview.
