Salam Miss Nasrine
thanks for your message and congratulations for you written success and good luck for the oral one
well this oral test each each is done differently , for examples last year in Médéa they asked teachers of English to speak just speak "in arabic" and the ones who were responsible of the exam were not inspectors of English , what I advise you is to be cool , speak correct English , be in you shoes , take your time to answer and you should be aware about the job of teacher its duties and rights and try to have a look at the Algerian legislation in order to have an idea about teaching in Algeeria
try to contact me through my email "it's on p48 web site and i will send you the document which concerns the legislation
good luck
