I was hired 2011 and the sequence of interviews and exams were different then twas exam, initial intervw then final. Now, i think it's initial interview then final interview.
But speaking from experience, I was asked about what my last area was while I was on my senior year in college (I was a fresh grad then..no experience ot whatsoever) and the questions were according to my initial answer. Example: pedia..so questions were about common management of fever, pneumonia, etc.. and how to assess children and babies.
For the final interview, it was either with the chief nurse or asst chief nurse..and it was more on whether you plan to proceed to Med..or if you're leaving out of the country anytime soon.. and what you did or what your job was before applying in Chong Hua. The trick is to make them feel like you're staying and you see CHH as a long term place of employment.
