By the way, recently I saw that there is a content creator who often talks about security vulnerabilities, and it seems that he even opens classes or courses for anyone about it. And I also saw that he said there are so many job opportunities about it, but even though you get a certificate after completing the course, they don't guarantee a job spot, it seems strange.
I can't access his social media profile because I don't have an account, but does he state that his certificate gives you a guarantee for a job spot? I don't think a certificate from popular cloud-based education platforms gives you that. I remember enrolling in a free lesson from Udemy and other platforms, and they don't give me any guarantee of securing a decent job. It's just one way to give your claims about your skill some proof. I think I can understand why because looking for a job in audit for smart contracts needs a high skill that requires more than a certificate of you passing a lesson about basic smart contract reading.
