Do certifications actually signal skill?

Sometimes. Rigorous certs (PMP, CPA, AWS Solutions Architect) do. Easy certs (online badges, clickthrough completion) do not. Employers know the difference.

Which certifications are worth it?

Industry-recognized (AWS, Google Cloud, Azure, PMP, CPA, etc.). Requires exam passing. Demonstrates commitment. Listed in job postings. Increases salary.

Can certifications replace experience?

No. Cert + zero experience = theoretical knowledge only. Cert + 2 years experience = credible expertise. Employers weight experience more.

What's the ROI calculation?

Cost (time and money) vs. salary increase. High-value cert (PMP, AWS): 6-12 month ROI. Low-value cert: never breaks even in salary gain.
