Credibility

Question

How credible is the certificate issued by this app on, say, LinkedIn to be considered valuable by potential viewers?

Answer 1

Soroosh Ahmadi though you can put them on LinkedIn it is always good to follow up with their certificates 'Linkedin' certs as well. This will help your profile and increase creditability. But by themselves I don't believe there is questionable but still you are saying to hr staff you have keyword "some" knowledge and interest in pursuing a) an internship or b) seeking additional schooling ....
