<p>It's never too early to attend, because you get a chance to talk to people working in different fields. You can find out about their jobs, advice they'd offer to get into the field, things they wish they had known when they were in college, etc.</p>
<p>For most people (who are liberal-arts majors) their career is not going to be something directly related to their major. This is both good and bad. The good is that virtually any field is open to the liberal-arts grad. The bad is that you won't walk into a job the same way a engineering or nursing major might.</p>
<p>With the whole world open to you, it's wise to start frosh year exploring different areas to see what feels right for you. There are many, many job areas out there that the typical college student has never heard of; their life experience so far hasn't exposed them to many areas outside of what their parents and other adults they know do.</p>
<p>My advice it explore as many avenues as possible, as early as possible. Take advantage of the resources of the career center (counselors, brochures, testing, etc), attend career fairs, employer presentations, join clubs, talk to alums in fields you're considering, etc. Done from the start it's a low-intensity process that allows time for blind alleys, changing your mind, etc. Waiting until spring of your senior year means a frantic process of trying to figure out what to do and the unhappy discovery others are far ahead of you in preparation and experience.</p>
<p>As for internships, they are perhaps the most useful way of standing out from the crowd of other applicants. Put yourself in the hiring company's shoes. Would you rather hire someone who says they think they'd like doing the job you're filling based on the description you posted at the career center, or the kid who spent a summer actually doing the work and can explain in detail why it's a good fit for them? In fact eperience in the field is valuable virtually no matter what your future plans are. For med school, an unwritten requirement for admission is volunteer work so that you've actually experienced what you're getting into. Top science PhD programs expect you to have done lab work undergrad; before they admit you for 5+ years of research they want to see you know what it's like. And so on.</p>
<p>I'd advise being a bit crafty about the whole internship "game". At the most prestigious companies the process is very selective. But you can get a leg up by having relevant work already. Suppose, for example, you are interested in a marketing internship the summer after your junior year at Proctor & Gamble. Very competitive. But if you work with the career center you can hatch a plan to get a summer job in marketing at a LA-based company after your soph year, so when you apply to P&G your resume stands out. And to help get that soph job perhaps you can find something after frosh year at an even smaller company.</p>
