Why did you become an engineer? 

I was inspired by frequent visits to my dad's electronic measurements lab when I was a child. My father was a physicist working for the Sri Lankan government. Interactions with my uncle who is a civil engineering professor also amazed me, and so many different fun engineering projects (like taking apart the family car) with my dad at home. I became hooked on electronics due to another uncle who was really into hi-fi equipment. These three people inspired me to pursue engineering as a career.
