What to wear and how to prepare for the first day of your internship.

The tech community is all a-Twitter with the story of a candidate who booted a new job with Cisco by Tweeting about how the commute — and the work — would be dreadful. You guessed it. Someone saw the post and the offer appears to have evaporated.

Dreams don’t come true if you stay asleep. You have to make things happen.

When you get hired as an intern, you are as a professional, but you come aboard as a person, too. The line gets blurred, quite naturally, when you make friends at work.

One of the best missed opportunities for many interns is the chance to find good mentoring. Some people drift into the internship, work hard and then disappear. Smart interns find mentors and stay in touch.
