Make talent quality your leading analytic with skills-based hiring solution.
An ethical hacker skills test checks whether a candidate can find, exploit and clearly report security weaknesses in systems they’re authorized to test. A strong test combines security fundamentals, hands on tasks such as web application and network challenges, and a written findings report. Glider AI’s Technical Assessments let you build this for entry level through senior roles.
Security hiring carries a particular risk. You’re giving someone deep access to your systems, so you need to trust both their skill and their integrity. Certifications help, but they don’t show how a candidate approaches an unfamiliar target, how carefully they stay in scope, or whether their report would make sense to the engineers who have to fix the issue.
Ethical hackers, often called penetration testers, are hired to attack systems with permission so organizations can fix weaknesses before criminals find them. Typical work includes:
| Skill area | What to test | Example task |
|---|---|---|
| Networking | TCP/IP, ports and services, firewalls, traffic analysis | Identify exposed services from a scan output |
| Web application security | OWASP Top 10, authentication flaws, injection, access control | Find and explain a vulnerability in a sample app |
| Operating systems | Linux and Windows internals, permissions, privilege escalation | Spot the misconfiguration that allows escalation |
| Scripting | Python or Bash for automation and custom checks | Write a short script to parse results |
| Cryptography | Hashing, encryption, common implementation mistakes | Explain why a password storage approach is weak |
| Reporting | Clear findings, severity, remediation | Write a finding for a nontechnical audience |
| Ethics and scope | Rules of engagement, legal boundaries | Respond to an out of scope discovery scenario |
Focus on fundamentals: networking, Linux, common web vulnerabilities and basic scripting. A 20 to 30 minute test with multiple choice questions plus one short practical task is enough to separate candidates who have practiced from those who’ve only read about security.
Add hands on challenges, such as a vulnerable web application or a set of logs to analyze, and require a short written finding. Score both the technical result and the clarity of the report.
Include scenario questions about scoping an engagement, prioritizing findings across a large environment, and explaining risk to executives. Senior candidates should show judgment, not just exploitation skill.
Score each section against a rubric agreed with your security lead, and weight reporting and ethics as seriously as the technical result.
Glider AI’s Technical Assessments cover 250+ technologies, so you can combine security, networking, Linux, scripting and cloud questions in one test that matches your team’s work. Hands on tasks show how a candidate actually works, and open ended answers such as written findings are scored against a rubric with a human override.
For security roles, integrity is part of the skill. AI Proctoring records tab switching, copy and paste, and face detection events for recruiter review, and questions are watermarked per candidate. ID Verify confirms the person who takes the test is the person who joins your team. Teams hiring security engineers at scale can see how this fits an enterprise hiring process, and engineering leaders can pair it with CI/CD skills checks for DevSecOps roles.
An ethical hacker should understand networking, Linux and Windows internals, web application security including the OWASP Top 10, scripting in Python or Bash, cryptography basics, and privilege escalation. Just as important are clear report writing and strict respect for scope and legal boundaries.
Combine a fundamentals section with a hands on challenge in a safe environment, a written findings report and an ethics scenario. Score each part against a rubric set with your security lead, and proctor the session so results reflect the candidate’s own work.
The terms overlap heavily. Penetration tester usually describes the job of running authorized security tests and reporting findings. Ethical hacker is a broader term for anyone using attack techniques with permission, including red team members and bug bounty researchers.
No. Certifications like CEH or OSCP show a candidate studied and passed an exam, and some are hands on. They don’t show how the candidate handles your environment, stays in scope or writes reports. Use certifications as a filter and a skills test as evidence.
Entry level tests can run 20 to 30 minutes. Mid level and senior assessments with practical challenges and reporting usually take 45 to 90 minutes. Keep each section focused so experienced candidates complete the test.
Use proctoring that records tab switching, copy and paste, and face detection, watermark questions per candidate, and verify identity before and after the test. Review flags with the session timeline rather than rejecting automatically.
The person you hire will hold the keys to your systems. Build a role specific ethical hacker skills test with Glider AI’s Technical Assessments and verify both skill and identity before you make an offer.
A recruiter screens a strong candidate on video, a hiring manager runs a solid technical round, and an offer goes out. On day one, the person who logs in is not the person who interviewed. Nobody on the team did anything careless. The process simply never confirmed who the candidate was. That gap is why […]
Introduction Technical roles are some of the hardest to fill. The process is a landmine of recruitment challenges. HR teams often find themselves under-resourced and struggling to find suitable talent, while engineers waste too much time interviewing candidates who don’t meet the necessary qualifications. Meanwhile, high-quality candidates get frustrated by slow and inefficient hiring processes and […]
What is QA and Testing? Quality Assurance (QA) and testing are integral processes in software development aimed at ensuring the reliability, functionality, and usability of applications. QA involves establishing standards and procedures to monitor and improve the software development lifecycle, focusing on preventing defects and identifying areas for optimization. It encompasses various activities such as […]
