How important is certification? [closed]

Certificate value:

• In the market: can help a resume selection for a HR , but practically nothing on the technical screen.
• For those who took decorating the answers of those sites that sell them: self-deception .
• For those who have struggled to take: deepening into a specific knowledge .
• In practice: very little importance if you are able to study on account, a little more important if you need a process to have study discipline.

Self-taught tip:

• It is cheaper to prove knowledge by participating in an open source project or by creating personal projects in GitHub, for example
• It's cheaper and more productive to buy good books on the subject of certification

A certificate is (to the market) a way to prove that you have certain knowledge, rather than impose on the contractor the burden of discovering and verifying it. Of course there are these points off the curve, but usually the certified professionals I know are endowed with well above average knowledge.

On experience, I agree that it is much more important than any role, but we are now standardizing our area, since so many outsiders (in management positions, RH ... ) needs to deal with IT professionals. Nothing more common than creating rules to make this work easier.

In addition to what has been said, that in large companies, which need to evaluate hundreds of curricula and the certificate is used as a criterion of cut (precise or not), I imagine that in other cases, for less weight that someone, or company, can assign for certification, it will always come as a plus point in your resume.

Let's say that only 2 candidates are running for a position in a company, no matter how personal the evaluation is, in cases where the evaluators consider that both candidates are equivalent, certification can be decisive.
