Well, the best way of getting into the field is by putting together a great portfolio. Emphasis on GREAT. I've spent the last 5 years as an art director for a newspaper, occasionaly I'll get portfolios sent to me and I have to say...I'm astonished at how horrible the work sent to me is.
I'm not trying to slam graphic designers here...what I'm trying to say from an art directors perspective- if you put together a kick butt portfolio you're going to be seen and remembered. When you read articles about the graphic design industry you'll see that they mention that competition is pretty intense. Not really, I really believe many people get into the graphic design industry is because they see it as 'easy' and a fun way to make a buck. They lack any real passion and zeal for design. The majority of portfolios I seen during our last hiring phase were from these people (about 20). However, I received 3 that really showed that they took time perfecting their presentation. What really impressed me about their portfolios was that each took an idea that could have been accomplished more simply but they took the time to think up some great, creative soloutions.
Choosing between the 3 was tough. Finally, I chose the one with the least experience but came with not only print designs skills but was fluent with web design also.
Trust me, putting together your portfolio will be the toughest thing about your new job. I know from experience. Expect sleepless nights, discouragement, depression, frustration....but eventually when you start to feel pride, excited, and confident, you'll know your portfolio is ready. Go get 'em.
Best of luck!
