Congratulations and thank you to smart guy. His first posting is correct and very helpful.
In my personal job search experience in California passing the bar exam is not helpful for finding a lawyer job in good law firm. If they like you they will hire you anyway even without bar admission and ask you to pass the bar next time. The reason for that is procedure, procedure and again procedure. The big law firms follow strictly very formal procedure by hiring lawyers. No exceptions. They come in September in the law schools and interview only the top 20 % of the second year JD students. LL.M's are not in this group and are not interviewed. Then they offered them summer associate job for two months in the summer before the third year in the law school followed in most of the cases by job offer for the time after graduation and taking the bar exam.
So the bad news for the LL.M's is that LL.M and passing the bar do not guarantee any lawyer job in US. It will be smarter first to spot the job and then to pass the bar exam. You don't need LL.M. However if you have extra funds and one year, LL.M will be great experience, fun, studying and great new friends from all over the world.
