Thank you for responding, I really appreciate it. I had a hunch that they want people with very specific skills. It makes sense from a business perspective.

I'm glad that it's just not me who has the feeling that I still don't know enough. For what I would like to do, I think i need full stack, definitely the front end stuff like html css javascript jquery, but probably node. Programming is so in depth that after studying it for the last few years, I have great respect for someone like you who has persevered and managed to be successful in the field.
