There's a difference between licensing and certification. A license is when the government says you need to meet some requirements to practice. A certification is when some entity, usually a board or industry group certifies that you are good enough at your job. We don't need licensing, but it would be great if we had broadly accepted certifications for software development. Even if you believe in FANG style interviews, ideally you should be able to pass one time and have it be accepted by every company. Once you have the certification, we could do interviews that focus on the type of things that individual teams and companies care about.
