Company Research Tips

1. Company Website Research

The official website of the police department you're applying to is a goldmine of information. Look for information about their mission, values, and culture. Understand their structure, the different departments, and the roles within them. Pay special attention to any recent news or press releases.

Tip: Don't just skim through the website. Take notes and try to understand how you, as a Detective Constable, can contribute to their mission and values.

2. Social Media Analysis

Social media platforms can provide a more informal insight into the police department. Check their Facebook, Twitter, LinkedIn, and Instagram accounts. Look at the type of content they post, how they interact with the public, and any recent campaigns or initiatives. This can give you a sense of their public image and community engagement, which are important aspects of policing.

Tip: Look at the comments and reactions to their posts. This can give you an idea of public sentiment towards the department, which can be a useful talking point in your interview.
