Can a shemale take an examination of civil servants? If not, is it sexist? If yes, what can be filled in the gender column? >

Your question is very interesting, but I can tell you clearly that the recruitment brochure for the public examination does not clearly stipulate that shemale can't take the exam!

But, you know, some political parties are dark. Even if you have passed the exam and the interview, you may not pass the physical examination.

On the surface, it is for you to take the exam. When you have a physical examination, just say that you are unqualified and you will be brushed off. This is normal! This is the darkness!
