I was pretty serious about pursuing forensic science as a profession. In fact, I pursued an internship at the office of the chief medical examiner here in New York.

As a medical doctor who chose a career in artificial heart technology rather than clinical practice, I decided not to take an internship, which is required for licensing. Instead, I work with invention, manufacturing, regulatory affairs, and clinical application of artificial hearts.

The downside to becoming a doctor, I think, is it's a very long process; four years of medical school, three years of internship, two years of residency, umpteen years of specialization, and then finally you get to be what you have trained almost all your life for.

Once I graduated college, I did a couple of different sort of unique internship positions, if you will. I spent three months in my mother's office, who was then the CEO of our company, and I really got to just sit in every meeting that she had, and I would write down questions on a yellow legal pad.

One goes through school, college, medical school and one's internship learning little or nothing about goodness but a good deal about success.

My first college internship was at Sony Pictures Entertainment in Los Angeles. My second internship was at McKinsey & Company as a consultant - that turned into my first job after graduation.

Nobody had ever told me junk food was bad for me. Four years of medical school, and four years of internship and residency, and I never thought anything was wrong with eating sweet rolls and doughnuts, and potatoes, and bread, and sweets.

Particularly with internships, you have to work for a year with no money. How on Earth are you going to finance that?

I think there is an enormous sea change happening in the global workforce. It has a lot to do with globalization. I think that people used to have a hope for a career or meaningful employment, and its been reduced to internships, part-time work or just grossly underpaid work.

Every company, regardless of size, is competing for the same pool of talent, which is why top recruiters can even command equity for finding key hires. Internships give startups a chance to hire the best and brightest from our universities at a fraction of the cost that these same minds will command when they receive their degrees.
