joseito21 - it's to your advantage to be a minority because it's a minority program.
1) the "partner firm" part of the application is mostly directed to the finance program candidates. basically they want to know if you're applying directly to an internship program at one of their partners as well as through SEO. where corporate law is considered, SEO isn't a parallel program - it's the only program.
2) It's OK if you're out of school and worked for a while. In fact it's probably a boost. You know how the real world operates, and thats a major asset.
3) They ask for all your academic credentials, where you get into, and where you're matriculating for mostly the same reason - the firms they're partnering include a number of the most selective firms in the country. The firms let SEO select and place all the candidates without their input. No doubt that in return there's an expectation on the part of the firms that the interns they get will reflect their targetted recruiting demographic - T14 schools.
4) No school is truly an autoadmit, but I'm fairly sure Berkeley clears a major hurdle for getting a slot.
As for NY/DC, SEO has been in NY for a long time, and just started in DC last year. Also the NY market is significantly larger anyway.
You won't really be asked about the firms during your interview. If you've done a lot of interviews, you'll know they tend to fall into two categories. There's the "friendly conversation" interview, and then there's the "bordering hostile/skeptical interview." SEO tends to the latter category. Know the traditional interview questions (why do you want this position? What makes you a better fit than anyone else? greatest Strength/Weakness, etc.) Have good answers for all the standard stuff. Know your resume - you will get asked about it. Especially any sort of gap. Also, this is a corporate law program - they asked me how I'd explain the lack of any business/econ/corporate experience on my resume to a legal recruiter. When I did the interview, they also asked you to read a newspaper article they'd give you and then you'd have to explain it coherently and answer some questions about it.
SEO is a great program, I learned a lot about the structure and nature of the industry. I felt super-informed when 2L OCI rolled around this year. Especially with the way the economy is now, this is a really solid leg-up. Go for it.
