What The Government Really Asks You - Pentester Interview

A behind-the-scenes look at what a real government cybersecurity interview is like: from 5G and 6G security to national defence research. Here’s what they ask, what they value, and how to stand out.

Pre-Interview Notes (From Recruiter)

This role was recommended by a recruiter. It is a government-focused position for national defence purposes, with a specialization in 5G and 6G applications and security.

The position is hands-on, as I would be experimenting with and securing new technologies, effectively handling advanced tools before they are deployed.


What They’re Looking For

For this position, the team is seeking someone who:

  • Is genuinely passionate about vulnerability research, with a willingness to learn telecoms, recognizing this is a very niche and specialized area.
  • Has previous hands-on security experience to demonstrate both commitment and the ability to learn new things.
  • Shows strong motivation for national security, which is logical given the government focus.
  • Can stay current with developments in the cybersecurity field.
  • Has an interest in cutting-edge technology.


How to Demonstrate Fit

  • Be prepared to discuss previous practical experience in cybersecurity, even if it isn’t directly related to telecoms or 5G/6G security.
  • Show that you are constantly learning and upskilling, which demonstrates both passion and commitment.
  • Whenever possible, have something tangible to show your work — for example:
    • Code samples
    • CTF writeups
    • Exploit research or vulnerability reports


High Performer in the Role

  • Focus on growth and learning, not just output.
  • The team functions like a research lab, valuing depth of understanding over speed.
  • Key traits for success:
    • Desire to learn and specialize in a particular domain
    • Ability to focus deeply and become an expert
  • Output is secondary; results naturally follow expertise.
  • For associates, the emphasis is on learning and skill-building.


Biggest Challenges the Team Faces

  • Enabler work tasks: foundational but necessary to support research.
  • Challenges in infrastructure development:
    • No prior research or tools exist for some aspects of Talecode or 5G.
    • Teething issues are expected when creating new tools and infrastructure.
    • Fuzzing over the air with 5G is largely uncharted.
  • Building systems and solutions that haven’t existed before.


Best Part of Working in Government Cybersecurity

  • Less focus on productivity metrics, more on depth and quality of results.
  • Projects allow for long-term investigations, targeting critical vulnerabilities.
  • Success is measured by one or two high-impact outcomes per project, rather than many smaller outputs.


Challenges for New Consultants (First 6–12 Months)

  • Learning Talecode, a highly specialized skill not taught at university.
  • Getting up to speed in a new domain (e.g., 5G, advanced cybersecurity concepts).
  • Adapting to pioneering research and working with unfamiliar tools.
