Let me start with answering your 2nd question first:
Yes, Qlik has similar courses for Qlik Sense as it has for QlikView.
The equivalents of the QlikView Designer and Developer are...
Create Visualizations (CV) and Data Modeling (DM).
If you already have experience with QlikView and/or have done the Designer and Developer training in the past, spending another 5 days doing CV and DM is a waste of your time and money. You are, in that case, not really a beginner. For this situation we have a dedicated 1 day training called "Qlik Sense for QlikView Developers".
Hope this answers your questions. If not, let us know .
In addition to Onno's suggestion of Qlik Sense training, we also have the Qlik Continuous Classroom (QCC)
The QCC offers self-service learning for Qlik Sense users 24/7. You can choose what you want to learn for all skill levels. New modules are added frequently and existing modules are updated as new versions of Qlik Sense are released.
