CERTIFICATION Courses vs Jobready Internships

5 Upvotes

While there is no comparison of both, but there is a clear gap in understanding of our youth we always go for easy options and choose to get certified as much as we can and collect certificates and heavily pay for it as well.

While communities like the one we are part of are really helpful but after doing all these free courses and getting certifications what is next ...

So thats why we created Jobready Programs.
