CO was very friendly and NOT intimidating. Interview was pleasant and more of a fun conversation rather than interrogation. CO just asked Melanie some basic personal questions such as what I like to do for fun and she just said watch TV and he asked what I like to watch. She replied NBA and car racing and he just laughed. He also asked her what attracted me to her and she replied it was her legs (true) and they laughed some more.
A lot of beneficiaries go for the interview and are very nervous. Melanie was not. She was confident as she knew that our relationship is genuine and it projected to the CO and she was easily approved without any issues.
