Also keep in mind the length of the process.
If you got called for your first interview now, you can expect around 6 to 12 months for the interview process (time from when you schedule first interview to when you are accepted). Then, you can likely expect 1 year wait to b offered a start date.
I waited 6-7 months for my start date, and guys who get through now are being told to expect a start date at the end of 2006. It is a lengthy process, but I think you will be happy with the end result.
