1) Lawdog, the salary figures do in fact range quite a bit, and are on a weekly basis (i.e. anywhere from 700 to 1000+ dollars a week). It depends on each employer.
2) prophecy, SEO does take a very conservative approach to working in the corporate world. It's a truism that the legal industry is a conservative one. SEO tends to take a somewhat extreme approach - the rule of thumb is that its always better to play it safe. SEO preaches a certain kind of conformity - you should be unremarkable in every way except your attitude, effort, and the quality of your work product, or as the unofficial motto goes "Do it better, do it faster, then ask for more." That being said, you might be able to pull it off if the dreads are relatively short, tied back, and you generally look professional etc. If you've got the credentials and attitude, the hair won't really be an issue (i.e. you're Harvard bound). In fact I'd say you'd be perfectly fine during OCI and any actual interviews in the future. FWIW, My class of SEO generally fit the minimal facial hair + generally short hair cut mold.
3) Lawdog, as to your concern about the impact of where you go to law school, I addressed the question a bit on the previous page. In short: where you get into school matters. A lot. T14 isn't a lock, nor is T15-20 an autoreject. But it's a numbers game and the preference for an academic pedigree is understandable considering the firms who participate in the program look for the same thing when they hire 2Ls.
