The digitalised BLNST is a computer-based version for degree/professional grades, launched in May 2025. It has the same format, duration and content as the paper-based test, but issues same-day electronic result certificates by email.

Typical stages include: physical fitness test, group discussion (often in Cantonese on current affairs), selection interview, and BLNST where appropriate. The exact sequence and components are detailed in the vacancy notice.

Practise discussing current affairs in Cantonese, focusing on structured arguments, active listening, and respectful interaction. Topics may relate to correctional services, public safety, or social issues. Demonstrate communication skills, judgement, and teamwork rather than dominating the conversation.

Expect questions on motivation, integrity, handling pressure, teamwork, role knowledge, and scenario-based judgement. For example: 'Why do you want to join the Correctional Services Department?', 'How would you deal with a non-compliant person in custody?', or 'Describe a time you maintained discipline under stress.' Answers should reflect public service values and safety awareness.

Discipline and security are fundamental. Assistant Officers II maintain order, enforce rules, conduct searches, prevent escapes, and ensure the safety of persons in custody, staff, and the public. They must apply regulations fairly and consistently while managing risks.
