I attended (and participated by asking questions and having conversations in) the UX and UI training sessions held by Atul Joshi of Design Incubator.

My thoughts on the UX and UI courses/workshops

I would personally recommend the Introduction to User Experience Design training course/workshop for desktop software professionals, web professionals and students who are interested in pursuing similar fields.

Mileage may vary with the Advanced User Interface Design training course/workshop. As I found my own design processes more effective (similar to how Coca Cola has its own secret formula, my own design processes is not public knowledge,) during the Advanced User Interface Design I have found more of a benefit in hearing about Atul Joshi's experiences and insights obtained while working in Indian markets and for Indian corporations when compared to markets and corporations in Europe, the USA and similar locations outside India.

New entrants, as well as yet to be seasoned professionals, in the design field could probably benefit more from the Advanced User Interface Design course than someone (such as myself) who has been Researching, Observing and Analyzing the field of Interaction Design and its related fields since Late 2007.
