The only advice I ever got about transitioning from a dev student to actually working in the dev world came when I was on my first semester in an elevator from a random person who already had a job in dev. Not her words, but paraphrased later by someone else:

"The only qualification you really need to make it just fine is the ability to utilise search engines better than the average gorilla"

... and she was right. Also, never before had I noticed, and I was dumbfounded when I did, how bad people actually were at searching for information.
