It depends

i read your question by accident, and i think the answer is: It depends on the organization you want to work for. You know even with a basic job, sometimes the boss want to challenge candidates a lot of times or just doing a test and negotiate the salary. Especially the job you mentioned abow. It seems like working as a lecturer. For more detail, you should contact to the organization which offer a candidate to work in that field. Each organization has its rule, its principle, its procedure... Sometimes they are quite different from the others.
