Interview Structure
Security engineer interviews typically cover: security fundamentals, hands-on exercises, system design, and behavioral scenarios.
Core Knowledge Topics
Cryptography
Understand encryption algorithms and their properties:
Interview question: Implement a secure password hasher
import hashlib
import os
def hash_password(password):
"""Hash password with bcrypt (the correct answer)"""
import bcrypt
salt = bcrypt.gensalt(rounds=12)
return bcrypt.hashpw(password.encode(), salt)
Follow-up: Why not SHA-256?
Answer: SHA-256 is fast, making brute-force feasible.
bcrypt/argon2 are deliberately slow and include salt.
Follow-up: What about MD5?
Answer: MD5 is broken for collision resistance. Never use.
Network Security
Interview question: Implement a simple port scanner
import socket
def scan_port(host, port, timeout=1):
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(timeout)
result = sock.connect_ex((host, port))
sock.close()
return result == 0
Follow-up: How would you scan without being detected?
Answer: Use SYN scan (stealth scan), randomize port order,
and introduce delays between probes.
System Design Questions
Design a Secure Authentication System
High-level design
class SecureAuthSystem:
components = [
"Rate limiter (token bucket per IP)",
"Account lockout (5 failures, 15 min lockout)",
"MFA enforcement (TOTP preferred)",
