If the trial lasts for say 3-5 months, I would miss all the interviews etc.
As other people here have said, don't worry. Unless you get chosen for another OJ trial, you're not going to be busy for 3-5 months.
I was on a jury a few years ago for a trial that lasted two weeks, and that was a rare long trial. The
vast majority only last a day or a couple/few days.
Depending on your state's rules (they all do it differently), here's also a good chance that you'll sit and wait for a day, but not get called to a trial. Or get called to a trial, but not chosen for the jury. Or check in from home and be told they don't even need you to come in that day.
When you do go, a judge will ask you if there's any reason the trial would be an undue hardship. If it does happen to be a long trial (but it won't!), you can explain your circumstances and the judge would probably reassign you to the pool for a different case.

All that said, I'm going to offer some different advice than most of the people in this thread:
don't try to get out of jury duty. Treat it as your responsibility, and take it seriously. Juries serve a crucial role in our legal system, and it depends on people who are willing to do their civic duty. Show up, be honest in answering the questions, and let the system work the way it's supposed to. Imagine that you were involved in a jury trial, either civil or criminal, on either side - and think about how important it would be to you that your jury was made up of people who believed in what they were there for, who were willing to be honest, openminded, and fair, who weren't just sitting there because they weren't able to get out of it.
Medicine is supposed to be about service, and we're supposed to be in it to help people. "I want to be a doctor because..." Think about how that relates to jury duty, and then think about whether you want to try to get out of serving. (And maybe you will be lucky enough to be chosen, and you'll come away with an experience to talk about in your interviews!)

[Steps off sopabox, takes a deep breath.] Hi everybody. Nice little rant for my first post to SDN, huh? I'll try to be good now.
And I'd be interested in hearing Law2Doc's take on this.
