I have seen many many people ... who are software engineers and they feel under estimated if they have to work as a designer. Many of my juniors express worda like, "I have my engineering and I m not happy working as a designer since I have done my software engineering". Most of the people who do engineering stick being an engineer and never try being something else. That was my point. where as me for instance, have worked on many areas tech support, designer, ,developer, customer service guy, computer repair guy, but work with UI since I like it the most. But what really matters is being open to exploring new things, but thats me. anyway.
