After mentoring dozens of aspiring cybersecurity professionals, I’ve identified the most effective paths into the field. Here’s everything I wish someone had told me when I started.
The Cybersecurity Landscape
Main Career Paths
| Path | Focus | Entry Roles |
|---|---|---|
| Offensive Security | Finding vulnerabilities | Penetration Tester, Security Researcher |
| Defensive Security (Blue Team) | Protecting systems | SOC Analyst, Incident Responder |
| Security Engineering | Building secure systems | Security Engineer, DevSecOps Engineer |
| GRC | Governance & compliance | GRC Analyst, Compliance Analyst |
| Security Architecture | Designing security | Security Architect (usually requires experience) |
My recommendation: Start with either SOC Analyst or Security Engineering—both provide broad exposure.

- “What’s the difference between TCP and UDP?”
- “How does DNS work?”
Security Concepts:
- “What’s the CIA triad?”
- “Explain defense in depth”
- “What’s the difference between encryption and hashing?”
Practical:
- “How would you secure a web application?”
- “Walk me through investigating a suspicious email”
- “What tools would you use to scan for vulnerabilities?”
Behavioral Questions
Use the STAR method:
- Situation
- Task
- Action
- Result
Common questions:
- “Tell me about a time you faced a challenge”
- “Describe a time you had to learn something new quickly”
- “How do you stay current with security trends?”
Prepare 5-6 STAR stories in advance!
The “I Don’t Know” Answer
Good answer: “I don’t know the answer to that, but here’s how I would find out…”
Then walk through your problem-solving process.
Bad answer: Making something up.
Common Mistakes to Avoid
❌ Certification Collecting Without Practice
Certs alone don’t equal job-ready. Build things.
❌ Only Studying, Never Applying
Start applying at ~70% ready. You learn on the job.
❌ Limiting Yourself Geographically
Remote security jobs exist. Expand your search.
❌ Copying Tutorials Without Understanding
Type out code, don’t copy-paste. Understand WHY.
❌ Neglecting Fundamentals
Can’t do advanced exploitation without networking basics.
❌ Not Networking
80% of jobs are filled through referrals. Network!
