Mongkok's clinic requires 14 workdays to receive the report, excluding the examination day. You MUST book the examination after receiving the original interview letter from the HK Consulate.
On the other hand, Central's clinic only takes 2 weeks to receive the report, and you do not need the original letter from the HK Consulate. You can bring the email from the HK Consulate that shows the interview date. However, it is advisable to use the query page to inquire with the HK Consulate first.
I eventually booked an appointment at Central's clinic where there were not many people. It was a very positive experience.
