Thanks for your input HallsofIvy. I personally found the first actuarial exam (1/P) to be much harder than the GRE math test, but I think the comparison is good. Someone with a good probability and statistics background might agree and I think it speaks highly of you that you felt they were similar difficulty.
I was hired with one exam passed (the second, FM/2, actually), and there are other examples of this. However, this has become increasingly rare. The general consensus is that students hired these days typically have at least two and often more exams. The first two exams are easier than the other exams and I’d suggest they be knocked out quickly to maximize the chance of employment. While pass rates are typically low (30%-50%, tending around 40%), the early exams are offered with increasing frequency and many applicants have several under their belt.
Most companies in the US have study programs, but they are very different than traditional classes. Students are essentially responsible for teaching themselves the material. There are seminars, but I found that these were not very helpful if I did not already know the material (but were very helpful improving my skills on material I knew). Most companies will pay for exam fees, study aids and a seminar, and also have a number of study hours. It is quite common to hear about actuarial students having difficulty finding time to actually take their study hours, especially at consulting shops.
