I applied through university. I interviewed at Hong Kong Transport Department
Interview
Three interviewers conducted the interview with me. questions asked are:
Self-introduction + questions based on CV (e.g. the courses related to the internship)+ your knowledge on hk transport system (easy basic knowledge)
will be good if you put forward some transport terminology
Two interviewers and around 30 minutes for the interview. In person interview. One of them is the engineer and the other one is senior transport officer. Average questions on most common things. Not that difficult. They usually hire equal number of each genders
