Hospital Authority interview questions

I applied this job through recruitment day. There were around 100 applicants in the lecture hall. The interview was one (me) to 9/10 (one hr + 8/9 hospital representatives). First, HR let me described myself within 1 minute. After that, both parties were SLIENT in 1 minutes. Then one representative asked me suitable for this job because I worked commercial field before and I have never worked HA previous. And I asked that representative working hours. Last, HR told me to leave. The whole interview procedure was within 4 minutes.

1 written test and 1 interview, quick proccess quite good. Interview will be facing 3-4 senior and each will ask some questions like why would you like to join etc
