My background is in Electrical and Electronic Engineering.
Last year I paid and attended android developer nano-degree by google course.
At the end of it I uploaded my capstone project on play store.
Now I am watching another course on Udemy called NodeJS - The Complete Guide (incl. MVC, REST APIs, GraphQL) which teaches you how to create node.js. applications. I have also attended two other Udemy courses regarding Android Development.
I applied for various android role positions, but didn't hear anything back. I was expected at least to be interviewed on my capstone's project code which is also in github. The code has been reviewed and works cool. Of course, I need to use at some point patterns like RxJava and MVVM.
But is all this considered as commercial experience or I wasted my money watching online courses?
