First of all you should have excellent CE and AL results.
I have been interviewed by the department of Pharmacy in 2003 (After SARS outbreak). The lowest requirement to get an interview is 24 marks in CE and AAB in AL. 'A's in CE and AL count the same. I have a friend with CE 25 marks and AAC in AL who had NOT been interviewed. So work hard. The question was the role of pharmacist in SARS outbreak. It was a group interview of 10 candidates and 5 professors/doctors.
The interview by the Medical Faculty for MBBS admission in CUHK asked for SARS. I can't remember the exact questions.
