>> My name is Raul Varia [assumed spelling].
I'm currently senior project engineer
at Underwriter's Laboratory in the Health Sciences Division.
I do medical devices certifications for a living right now.
The challenges, I think most of the people that I have met in the industry
or in the other industry -- I used to be at IT Cisco before --
as soon as you lose the challenge portion of the job, then they lose interest.
So if the more challenging it is, not too challenging because some people don't
like it too challenging, but as long as the challenges keep going,
then you will always find yourself happy and comfortable.
