Update: DTV approved after interview in Karachi embassy.
The ambassador was very nice, friendly, and shared some pro tips as well. When I entered, he mentioned that the ministry has asked me to check your contracts (I work on Upwork as a full time freelancer). After I showed him my profile live with a few contracts, he stopped me and said, "that's enough, I'm satisfied." I asked him a few questions regarding the visa and then left the embassy.
In 90 mins, I got my visa on email. Alhamd o Lillah
