  • Understanding of network protocols and information security principles
  • Problem-solving skills and the ability to think like an attacker

Interview Plan for an Ethical Hacker:

Round 1: Screening and Skills Evaluation (30-45 minutes)

Objective: Assess the candidate’s background, experience, and basic understanding of ethical hacking and cybersecurity concepts
  1. Questions:
    • How did you become interested in ethical hacking, and what led you to pursue a career in this field?
    • Can you explain the difference between black, white, and gray hat hackers?
    • Describe your experience using security tools such as Nmap or Metasploit.
  2. Expectations: Candidates should be able to describe their backgrounds, experiences, and motivations, as well as display familiarity with core cybersecurity concepts and tools.

Round 2: Technical Assessment (60-90 minutes)

Objective: Evaluate candidates’ technical knowledge, problem-solving skills, and ability to reason through security challenges
  1. Technical details:
    • Evaluation of programming and scripting skills, particularly in Python, Ruby, or PowerShell
    • Understanding of network protocols and data manipulation techniques
    • Proficiency in using security tools and frameworks during penetration testing
  2. Questions/Exercises:
    • Explain how you would execute a port scan using Nmap, and what information you expect to gather.
    • How would you use a Man-in-the-Middle (MITM) attack to intercept and modify data between two parties?
    • Write a basic Python script that performs a basic system reconnaissance activity.
  3. Expectations: Candidates should be able to apply their technical skills to solve realistic cybersecurity problems, demonstrating the depth of their knowledge and ability to reason through challenges.

Important Notes for the Interviewer

  • Focus on evaluating candidates’ ethical approach to hacking, ensuring they have a clear understanding of legal boundaries and professional guidelines
  • Consider asking open-ended questions about how candidates would handle potential ethical dilemmas or conflicts of interest
