Recently trying to schedule with a provider who uses video chat for screening. Although I don't know what she will ask me, I'm not sure about using this process. Anyone used video chat or zoom to screen?

Perhaps this is the virtual equivalent of that?

i wouldnt do any video chat. 99% of the time its just to get you to pay for camming.

I have tried to contact multiple in my location via email. Zero response. I ask about location and available times. What am I doing wrong?

If she is well reviewed or well known.
.
If not, everything she records can be used as blackmail material.
