Different Certifications

You need to remember that a course completion certification is very different from Oracle's Java certification or AWS certification from Amazon, which really tests your skill and then awards your certificate.

The certifications listed above are definitely more valuable than a standard course completion certificate from Udemy, Coursera, edX, Educative, or Udacity.

Coursera or Udacity certificates offered by Google, Microsoft, or Stamford University are much more valuable than a random certificate as these firms enjoy a lot of trust in the public's eye.
