Top 10 Security Interview Questions & How to Answer Them
How Security Interviews Work
Security job interviews are typically straightforward compared to other industries. Employers want to assess three things: can you be trusted, will you show up reliably, and can you handle difficult situations calmly?
Most interviews last 20 to 40 minutes and are conducted by an operations manager or site supervisor. Here are the 10 questions you are most likely to face, with guidance on how to answer each one.
1. "Tell me about yourself and your security experience."
This is your opening. Keep it focused on your security career, not your life story.
Example answer:
"I have been working in the security industry for two years. I started as a door supervisor at a bar in Sheffield, then moved to a nightclub where I managed a team of four door staff on Friday and Saturday nights. I recently completed my first aid qualification and I am looking for a full-time security role that gives me more consistent hours and the opportunity to develop into a supervisory position."
Key points: Mention your SIA licence, specific experience, and what you are looking for next.
2. "Why do you want to work in security?"
Employers ask this to filter out people who see security as a last resort. Show genuine interest.
Example answer:
"I am drawn to the responsibility that comes with keeping people safe. I enjoy the problem-solving aspect — every shift is different, and you need to stay alert and make quick decisions. I also like the clear career progression in security. I have seen people go from guard to manager within a few years, and that is the path I want to take."
3. "How would you handle an aggressive individual?"
This is the most important question. Your answer reveals whether you understand de-escalation.
Example answer:
"My first approach is always to de-escalate verbally. I would stay calm, maintain a non-threatening body posture, make eye contact, and speak clearly and respectfully. I would try to understand what has upset the person and see if there is a way to resolve it. If they are intoxicated, I would suggest they sit down and offer them water. I would only consider physical intervention as an absolute last resort if there was an immediate threat to someone's safety, and I would always stay within the boundaries of reasonable force. I would also make sure to call for backup early rather than trying to handle a volatile situation alone."
Never say: "I would restrain them" or "I would remove them immediately." Employers want to hear de-escalation first.
4. "What would you do if you caught a colleague sleeping on shift?"
This tests your integrity and understanding of professional standards.
Example answer:
"I would wake them up and make sure they were alright — there could be a medical reason. Then I would remind them that sleeping on duty is a serious breach and puts the site at risk. I would document it in my shift report because it is my responsibility to report accurately. I would not try to cover for them, but I would handle it professionally rather than confrontationally. If it became a pattern, I would raise it with our supervisor."
5. "Can you give an example of a time you dealt with a difficult situation?"
Use the STAR method: Situation, Task, Action, Result.
Example answer:
"At a nightclub I worked at, two groups of about six people each started arguing near the bar area. The situation was escalating quickly. I positioned myself between the groups with another colleague, made eye contact with what seemed to be the leader of each group, and calmly but firmly told them that we needed them to separate. I directed one group to the other side of the venue and stayed with them until things calmed down. No one was ejected, no one was hurt, and the night continued without further issues. My manager specifically mentioned it in my review as an example of good de-escalation."
6. "What does your SIA licence allow you to do?"
This checks whether you actually understand the legal framework you work within.
Example answer:
"My door supervisor licence allows me to work in roles that involve controlling entry to licensed premises, conducting searches, and managing security at venues where alcohol is served. It also covers most security guard roles. I understand that working without a valid licence is a criminal offence and that I must display my licence visibly while on duty. I also know that my powers are limited — I am not a police officer, and any physical intervention must use only reasonable force."
7. "How do you stay alert during a long shift?"
Night shifts and long static posts test your endurance. Employers want to know you will not switch off.
Example answer:
"I stay active by following a patrol routine and varying my routes so I am not walking the same path every time. I keep hydrated and eat properly before and during shifts. On static posts, I set myself mental tasks — checking different areas of the CCTV systematically, reviewing access logs, and writing up observation notes. I also find that staying engaged with colleagues by radio helps maintain alertness. If I ever felt genuinely too tired to do the job safely, I would inform my supervisor rather than risk the site."
8. "What would you do if you discovered a fire?"
This assesses your knowledge of emergency procedures.
Example answer:
"I would follow the site fire procedure. In general terms: raise the alarm by activating the nearest call point, contact the emergency services on 999, begin evacuating people from the area using the nearest safe exit, and then report to the designated assembly point. I would not attempt to fight the fire unless it was very small and I had the correct extinguisher. My priority is always human safety first, property second."
9. "Are you comfortable working nights, weekends, and bank holidays?"
Be honest. If you have genuine restrictions, say so now rather than causing problems later.
Example answer:
"Yes, I am fully flexible and happy to work any shift pattern. I understand that security is a 24/7 industry and the most important shifts are often the unsociable ones. I have worked nights and weekends in my previous roles and I manage my sleep schedule to make sure I am always alert on shift."
If you have restrictions: "I am available for nights and weekends, but I have a commitment on Tuesday evenings that I cannot change. I am happy to work around that in every other way."
10. "Do you have any questions for us?"
Always ask questions. It shows engagement and helps you assess whether the role is right for you.
Good questions to ask:
- "What does a typical shift look like on this site?"
- "How many guards are on site during a night shift?"
- "What training and development do you offer?"
- "What is the team like here — how long have most people been in the role?"
- "Is there opportunity for overtime or additional shifts?"
