No, not needed as you have to come back in person to be approved or rejected. They told me I had an interview when I came back to hear if they approved the application.
I just gave my regular numbers. No questions on your stay in Taipei as well.
Exactly, they are concerned about doing the same work and very much focused on non Thai connection with work. I was surprisingly called for an interview for clarification on my job and that I would only be working with non-Thai clients.
