6.5Certifications: What Matters and What Does Not

Certifications in QA are controversial. Some hiring managers value them. Others consider them irrelevant. The truth depends on the certification, the context, and the rest of your profile.

Certifications Worth Considering

Certification	Value	When It Matters
ISTQB Foundation (CTFL)	Standardized testing vocabulary and concepts	When applying to enterprises, European companies, or roles that specifically require it
ISTQB Advanced (CTAL)	Deeper testing methodology	When pursuing senior roles in organizations that value formal methods
AWS / Azure / GCP certifications	Cloud platform knowledge	When working on cloud-based testing, DevOps, or infrastructure
Security certifications (CEH, OSCP)	Security testing credentials	When pursuing security testing specialization
Kubernetes (CKA/CKAD)	Container orchestration	When testing microservices or working closely with DevOps

Certifications That Are Mostly Resume Filler

• Vendor-specific tool certifications (e.g., "Certified Selenium Tester") -- these test tool usage, not testing skill
• Certifications from unknown or unaccredited organizations
• Certifications that anyone can pass with a weekend of studying

The Certification Principle

Certifications open doors. Skills keep you in the room. A certification might get your resume past an HR filter, but it will not help you in a technical interview or on the job. If you have limited time, invest in actual skills first and get certifications strategically when they serve a specific goal (e.g., a job you want requires ISTQB).
